4 SO WE MAY BE BETTER KNOWN It was in 1957 when Vittorino and Dorino Tognella decide to set up the F.lli Tognella s.d.f., after years of experience acquired in a well-known local firm which operated in the aeronautics field. In creating this new company they invested their skills in the most sophisticated mechanical concepts, their knowledge of the different problematics of the economic and productive field, their entrepreneurial spirit, willpower, determination, technique and great technical experience. They started mainly as sub-suppliers of firm operating in the neumatics field. The they gradually made a place for themselves in the hydraulic fields which became, through a winning choice, the predominant sector of their activity. 2

5 Technology is firmly rooted in the past, dominates the present and is projected towards the future The challenge F.lli Tognella S.d.f. accepted was not easy to win : To offer quality products at the right price. But even in the competition with international giants, their precision, firmness, well-balanced administration and a complete reinvestment of the profits rapidly transformed this firm into a protagonist of the market. Never much influenced by the rapid changes this sector has usually undergone, being always able instead to anticipate the requirements of its customers, day after day the firm grew and in the Seventies it gained widespread consent all over the world. The spreading of Tognella products has by now reached a worldwide scale, being present in over 35 countries and in various industrial, commercial and service sectors : from mechanics to machine tools, to earthmoving machines and agriculture, from plastics to marble and wood working and to materials handling and many other fields The success achieved does not however represent for the company a final point, but it is rather considered as an element of endless evolution that leads to new ways and ideas, new products and projects in harmony with the most advanced technologies. 3

6 NOT JUST A CATALOGUE It is a modern-style publication which we consider more than a simple catalogue. Therein are described specific data of each product, as well as the technical data necessary for a correct choice of the various components depending on the different applications that they are intended for. It is composed of various chapters according to the different valve types and the initial index allows quickly consultation. The intention was to provide the catalogue with a dual purpose: technical and advertising so as to be a valid instrument of consultation as much as for the technical offices, as for the users and the distributors who will find satisfaction to their obviously different requirements. We would be sincerely grateful to all those who kindly pass on to us any criticism, suggestions, advice or whatever else might be useful to the improvement of this publication with the aim of making it suitable to find the appreciation of our clients. 4

7 BIG ENOUGH TO DARE A WORLDWIDE CHALLENGE: FAIRLY LITTLE TO SATISFY OUR CUSTOMERS REQUESTS AT THE RIGHT TIME. The Tognella Spa, conscious of the difficulty of remaining competitive on the market with just one product, in order to widen its offers and proposals and convinced of the necessity of satisfying its acquired and potential customers with products and services, has created a team able to comply with the more different and changeable demands from an always growing market by the standard production and the realization of components and special customized equipments, both with changes on existent products and with completely new construction. In 02 pursuing its aim Tognella S.p.a. acquires the 50% of the share of COSTANTE SESINO S.p.a., leader in the production of standard and special water-oil and air-oil heat exchangers. The company starts its activity in 1919 with the production of car radiators for customers like FIAT and Autobianchi and, thanks to successful technological entrepreneurial choices, it arrives to the present production consisting of exchangers. The recent difficulties of the market has caused a stagnation in the activity. But at the right time Tognella S.p.A. has decided to invest not only in the new building but also in new 5

All this has contributed to strengthen its image on the suitable market. NATIONAL SYSTEM S.r.l., is a quite new company which offers its advice for non-destructive analysis instruments particularly

8 machines and equipment. It has also taken into consideration the commercial aspect and has tried to give a new image of itself by taking part to exhibitions and by increasing the range of its products. All this has contributed to strengthen its image on the suitable market. NATIONAL SYSTEM S.r.l., is a quite new company which offers its advice for non-destructive analysis instruments particularly by planning and realizing automatic test stations, acoustics and vibrations analysis systems, measuring, control and regulation systems and data logging on destructive systems. Recently it has acquired LAMETARS 05 S.r.l., factory that produces plastic components for the electrical appliances industry and metallic ones for other industry sectors. The creation of this structure is a part of our mission and together with our professionalism, competence, experience, efficiency and dynamism, has the aim to catch in advance our customers needs trying to satisfy them. We are in a position to declare that guiding line is the increasing and constant owners care who reinvested the profits and have always believed in the company capacities, in the products validity and the image promotion. 6

9 50 years, but it does not show them 50 years of efficiency, dynamism, flexibility, courtesy offered to our customers. For over 50 years we have been making valves, which did not passed unnoticed. Tognella has always been characterized by its originality, essentiality and reliability : in other words, the quality of its products. This has always proceeded at the same rate with an intense productive activity always keeping market requirements well in mind, continuously following new directions, developing products able to satisfy customer demands and expectations. Proof of all this is the additional contribution provided by second generation of the entrepreneurial Tognella s family to the development of the firm. The new company site has in fact been recently built on an area of over sq,m with nearly total replacement of all machinery and with the introduction of automated systems, equipments and the most updated assemblying and monitoring systems. All these elements lead the firm into the XXI century with all the requirements for future business success, not to be dragged by the events but wishing to manage them. 7

25 IN LINE SINGLE-ACTING CONTROL VALVES Their function is to control and, if necessary, to shut-off the flow in one direction, allowing a free return flow in the opposite direction. Appreciated for their aesthetic characteristics, they are a reliable solution. The suitable dimensioning has made possible to obtain, in a little space, a great mechanic resistance of the components. The spring in high-resistance material is housed in such a way that it does not close as a pack during the opening of the single-acting conical valve poppet. Like all the valves of the series FT 257 they ensure: metallic seal; flow linearity at the opening; accurate control for a wide range of flow rate, thanks to the double reference system wide range of the flow rate control; impossibility for the needle to leave its seat even in the max. opening position; stable positioning thanks to a dowel inside the knob; quickness in the assembling of the panel (the ring nuts (G) are supplied on request).

31 CHECK VALVES (PISTON) They are inserted in branches of the circuit where the free flow in one direction is allowed and the return flow in the opposite direction is not possible. A lasting and hermetic seal is ensured by the conical valve poppet, which is a reliable mechanical solution. The spring in high-resistance material is housed in such a way that it does not close as a pack during the opening phase. The external configuration of the body makes it easy to seize the piece during the assembling. They are available with different calibrations of the load pressure (0,5 standard and s).

47 DOUBLE-ACTING PRESSURE COMPENSATED FLOW CONTROL VALVES Double-port pressure compensated control valves They include two necks in series: the first one with port section definable by an external control; the second one with automatically variable section in relation with counter pressure variations on use. The choice of the adjustable neck situated upstream is that which best ensures the precision of the valve towards variations of the fluid temperature. Regarding the structure of the valve, the following points must be underlined: the rigorous symmetry of the internal components such as to impede unforeseen perturbations of the static and dynamic balances; the optimisation of the arrangement of internal spring controlling the intervention of the automatic throttling, with variable preload with throttling fixed setting, useful to improve the behaviour at medium-high flow rates; the geometry of the passage across which the flow is automatically throttled, designed to minimize the effect of the flow hydromechanics forces on the total balance of the moving element; the accuracy of the machining which enabled to cancel any hysteresis effect of mechanical origin; the original aesthetic feature, underlined by the particular form of the control knob; the easiness to reset the flow value thanks to reference pointers. Moreover we believe important to underline the choice of the constructive solution fitting to the concept of double valence, according to which the central body, configurated as a threaded cartridge and insertable in the two different bodies at the base or directly in standard modular units, brings about the three marketed versions: FT 277/2 two-way FT 277/5 two-way with single-acting valve FT 287/2 with threaded cartridge mounted.

91 CARTRIDGE PRESSURE COMPENSATED FLOW CONTROL VALVES Pressure compensated flow control valves, to insert in modular units in line. They are essentially composed of the central body of valves series FT 277/2 which may be screwed in units preset by the user. The construction and functional characteristics reflect exactly those described for the two inlet valves. It is recommended to keep them in their protective wrapping until the mounting, in order to avoid possible drawbacks caused by eventual entry of particles into the delicate and essential parts for a good working. On page 94 is proposed a machining scheme for the embedding seat, which has to be observed to ensure the necessary accuracy of the valve. The constructive system allows the user, already provided with those versions, either to request the two inlet base bodies only, so as to allow their quick transformation, or to store the single standard components to assemble in the various types according to the need.

107 CARTRIDGE MOUNTED PRESSURE COMPENSATED TWO-WAY LOW FRICTION CONTROL VALVES MAX 350 BAR Pressure compensated flow control valves, to insert in modular units in line. The construction and functional characteristics reflect exactly those described for the two inlet valves. It is recommended to keep them in their protective wrapping until the mounting, in order to avoid possible drawbacks caused by eventual entry of particles into the delicate and essential parts for a good working. On page 0 is proposed a machining scheme for the embedding seat, which has to be observed to ensure the necessary accuracy of the valve.

STACKABLE VALVES CETOP 03 3-WAY PRESSURE COMPENSATOR WITH LOAD SENSING FUNCTION The valve is a 3-way pressure compensator, with direct action, realized in modular version with interface surface

It is normally used in combination with the directional valves with proportional control so that it is possible to realize flow rate controls, which are independent from pressure changes.

c ADJUSTMENT OF REDUCED PRESSURE The calibration of the valve FT3-LS-P3 is useful to calculate the range of the use flow rate.

173 STACKABLE VALVES CETOP 03 3-WAY PRESSURE COMPENSATOR WITH LOAD SENSING FUNCTION The valve is a 3-way pressure compensator, with direct action, realized in modular version with interface surface corresponding to CETOP and ISO standards. When using this kind of valve, a constant pressure drop (characteristic Dp) between the P-way and alternately the A-way and B-way is held. It is normally used in combination with the directional valves with proportional control so that it is possible to realize flow rate controls, which are independent from pressure changes. The selection of the pilot pressure on the A-way and B-way is carried out automatically through a bistable check valve inside the compensator. c ADJUSTMENT OF REDUCED PRESSURE The calibration of the valve FT3-LS-P3 is useful to calculate the range of the use flow rate. According to a non-linear law, if DP increases, the value of the compensated flow rates, which pass through the adjusting mechanism increases too, and this does not depend on the operating pressure of the system. Ex. In a system like that shown in A, consisting of FT3-LS-P3 plus proportional valve HD3-PS-3RC-xx (see table HD-3), with DP of 1MPa ( ), the flow rate to the actuator changes between 0 and 16, with DP of 3MPa (30 ) the flow rate to the actuator changes between 0 and 28 (this does non depend on the value of the system working pressure). To improve the system operation it is essential to adjust the DP of the compensator. By operating with CH5mm on the adjusting pin 2, after loosing the check nut 1 at CH17mm the DP of the compensator is adjusted. It is recommended to loose completely the spring, by turning (anticlockwise till the mechanical lock) the threaded pin 2 at pitch 1,25mm. By screwing clockwise: DP = 0,4 MPa (4 ) stroke 2,5 mm* (2 rev.) DP = 1,2 MPa (12 ) stroke 3,75mm* (3 rev.) DP = 2,1 MPa (21 ) stroke 5 mm* (4 rev.) DP = 3 MPa (30 ) stroke 6,25mm* (5 rev.) DP = 3,9 MPa (39 ) stroke 7,5 mm* (6 rev.) * including an initial dead stroke of about 2mm (1,5 rev.). When the required calibration is reached, tighten the check nut with CH17mm.

177 STACKABLE VALVES CETOP 03 2-WAY PRESSURE COMPENSATOR 2-way pressure compensator. When using the 2-way pressure compensator, a constant pressure difference across the metering edge of the proportional direction valve is held. In this case, the pressure variations due to loading changes, as well as pump pressure changes, are compensated. This means that an increase in pump pressure cannot result in any flow increase. Provided that there is no preloading of the outlet port, the use of a meter-in pressure compensator is limited only to drives with exclusively positive load direction c CONTROL OF THE FLOW Valves FT3-PC-* are directly operated 2-way pressure compensators. The main parts of these valves are the housing (1), control spool (2), spring (3) and logic valve (4). The spring (3) holds the spool in the open position from P2 to P1, provided that the pressure difference between P1 and A (P1 - B) is less than (P =. When the pressure difference exceeds the value (P =, the spool shifts against spring until the requested pressure difference has been restored.

P = (P1 P2) γ water = 1 Q = Kv 1 P γ acqua FORMULA TO OBTAIN THE VALVE FLOWRATE P = P1 - P2 γ Difference between downstream and upstream valve pressure () Relative water density Kv Valve coefficient depending on inner valve geometry. This value is obtained experimentally. Example To determine the water flow rate in L/min with a valve FT 1251/2-12 with Kv = ) VISCOUS LIQUIDS Z = ν Q Kv Q ν Kv ν = 23 centistokes γ water = 1 Kg/dm 3 P = 2 L Q = 8O = 4.8 m min 3 /h Q Kv1 = P γ acqua Kv2 = Kv1 P γ Q = L min Z PARAMETER Kinematic viscosity in centistokes Valve flow rate in mc/h Valve coefficient in mc/h L 1 Kv1 = min Valve coefficient L/min Downstream pressure Upstream pressure Pressure difference Relative water density Portata in L/min Il coefficiente Kv della valvola deve essere moltiplicato per un fattore F>1 quando siamo in presenza di un liquido viscoso.

278 FLOW RATE CALCULATION IN FUNCTION OF THE VALVE KV COEFFICIENT 3) Gas FORMULA TO OBTAIN THE STANDARD VALVE FLOW RATE (N-LITER/MIN) Qn = Kv K Kv = 15.4 L min. T1 = 273 K + t γ nitrogen = kg m 3 T1 = 293 K kg γ air = m 3 γ nitrogen γ relat. = γ relat. = γ air P2 P crit. = P crit. = P1 Qn = Kv P1 - P2 γ relat. Qnmax = Kv P1 P = P1 - P2 T1 γ γ air γ relat. P1 - P2 γ relat. P2 T1 Qn1 = Qn x 60/00 = Nmc/h P2 T1 1 γ relat. T1 Qn = L min Qn1 = 5 Nmc h The formula is valid till the ratio P2/P1 does not go under the value P2crit./P1, corresponding to the sonic flow. For ratio of P2/P1 inferior to such a value, flow remains constant. As the value P2crit./P1 is about 0.5: the formula of the max. flow rate for gas is obtained through the following formula FORMULA PER RICAVARE LA PORTATA MASSIMA DELLA VALVOLA (N-Litri/min) Difference between downstream and upstream valve pressure () Absolute gas temperature upstream the valve Gas density Air density Relative gas/air density Example To determine nitrogen flow rate at C with P1 = 7 and P2 = 5 on the valve FT 1251/2-12 Valve coefficient Absolute temperature Nitrogen density Air density Relative density Critical pressure (for values superior to 0.5 use the following formula) Flow rate in NL/min Flow rate in Nmc/h MASS FLOW RATE FORMULA TO DETERMINE THE VALVE MASS FLOW RATE G = Qn1. γ So we obtain G = Qn1 γ nitrogen G = kg h Valve flow rate kg/h 276
