Data sheet Hand operated regulating valves Types REG-SA and REG-SB REG-SA and REG-SB are angleway and straightway hand operated regulating valves, which act as normal shut-off valves in closed position. The valves are available in two different versions REG-SA and REG-SB designed for regulation purposes in liquid and expansion lines. The valves are designed to meet the strict quality requirements on refrigerating installations specified by the international classification societies and are carefully designed to present favourable flow conditions and accurate linear characteristics. REG-SA and REG-SB are equipped with vented cap and internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure. Features Applicable to HCFC, HFC, R77 (Aonia), R7 (CO ), Propane, Butane, Iso-Butane and Ethane. Modular Concept: Each valve housing is available with several different connection types and sizes. Possible to convert REG-SA or REG-SB to any other product in the Flexline TM SVL family (shut-off valve, check & stop valve, check valve or strainer) just by replacing the complete top part. Fast and easy valve overhaul service. It is easy to replace the top part and no welding is needed. Designed to ensure perfect regulation Internal backseating enables replacement of the spindle seal whilst the valve is active, i.e. under pressure. Easy to disassemble for inspection and possible repair. Long neck versions (DN 5 to DN ) for insulated systems available from parts prograe. Max. operating pressure: 5 bar g (75 psi g) Temperature range: 6/+5 C ( 76/+ F) Acts as a normal shut-off valve in closed position. Housing and bonnet material is low temperature steel according to requirements of the Pressure Equipment Directive and other international classification authorities. Exact capacity and setting of the valve can be calculated for all refrigerants by means of Coolselector (Danfoss calculation and selection software). Classification: DNV, CRN, BV, EAC etc. To get an updated list of certification on the products please contact your local Danfoss Sales Company. Danfoss DCS (MWA) 6. DKRCI.PD.KM.A9. 5H6

Material is special, cold resistant steel Connections Available with the following connections: Butt-weld ANSI (B 6. Schedule 8) DN - ( / 8 - ½ ) Butt-weld ANSI (B 6. Schedule ) DN 5-65 ( - ½ ) Socket weld (ANSI B 6.) DN 5 - (½ - ½ ) FPT inside pipe thread, NPT (ANSI/ASME B..) DN 5 - (½ - ¼ ) The cone The valves are available in two different versions REG-SA with an A cone and REG-SB with a B cone. The A cone is designed for expansion lines, while the B cone is designed for regulating purposes e.g. liquid lines. The valve cone is designed to ensure perfect regulation and provide an extensive regulating area. Irrespective of the refrigerant used, it is easy to obtain the correct capacity. A cone seal ring provides perfect sealing at a minimum closing momentum. The valve cone can be turned on the spindle, thus there will be no friction between the cone and the seat when the valve is opened and closed. Spindle The spindle is made of polished stainless steel, which is ideal for O-ring sealing. Packing gland - REG-SA and REG-SB The full temperature range packing gland ensures perfect tightness in the whole range: 6/+5 C ( 76/+ F). The packing glands are equipped with a scraper ring to prevent penetration of dirt and ice. Installation Install the valve with the spindle up or in horizontal position. The flow must be directed towards the cone. The valve is designed to withstand high internal pressure. However, the piping system in general should be designed to avoid liquid traps and reduce the risk of hydraulic pressure caused by thermal expansion. For further information refer to product instruction for REG-SA and REG-SB.

Computation and selection Introduction In refrigeration plants, hand operated regulating valves are primarily used in liquid lines in order to regulate the flow of refrigerant. The valves can, however, also be used as expansion valves. From a calculation point of view the two fields of application are very different. Normal flow is the term used to describe the general case where the flow through the valve is proportional to the square root of the pressure drop across it and inversely proportional to the density of the refrigerant (Bernouillis equation). This relationship between mass flow, pressure drop and density satisfies the majority of all valve applications with refrigerants and brines. Normal flow is characterised by turbulent flow through the valve without any phase change. The following capacity curves are based on the above mentioned assumption. Application of the hand operated regulating valves outside the normal flow area will reduce the capacity of the valve considerably. In such cases it is recoended to use Coolselector (Danfoss calculation and selection software).

Computation and selection Example. Refrigerant: R 77 Refrigerant flow: kg/h Pressure drop: p =.5 bar The above mentioned example is illustrated on the following flow rate diagram and shows that REG-SB 5 and with cone B can be used. The main rule is that nominal regulation range should be below 85% opening degree. If the arrowline is crossing cone curves, the smaller cone should be selected if opening degree < 85%. The example is only correct if the density of the refrigerant is approx. 67 (kg/m ), and there must be no build-up of flash gas in the valve.

Computation and selection Example. Brine, density ρ: 5 [kg/m ] Brine flow G:,7 [kg/h] Pressure drop p:.5 [bar] In this example it is not possible to use the selection diagrams (fig. 6 - ) as the refrigerant in question is not included. Use the curves of the k v-values instead (fig. - 5) and calculate the required k v by means of the formulas in the "Introduction" passage at the beginning of this chapter. Alternatively calculate the k v-values by means of the calculation factor C A (fig. ) and the flow rate diagram (in this example: fig. ) as per the following calculation example.
