During this time, more than 2, valves have been delivered. hese servo- and pro p o rtional control valves have been pro v e n to provide reliable control for injection and blow molding equipment, die casting machines, presses, heavy industry equipment, paper, lumber processing, and other applications. R O O RIONL CONROL V LVES, D681 O D685 SERIES he D68 Series ro p o rtional Flow Control Valves are thro t t l e valves for 2-, 3-, 4- and 5-way applications. hese valves are suitable for electrohydraulic position, velocity, p re s s u re or force control systems, including those with high dynamic response re q u i re m e n t s. With the new D633 Series directly driven pilot valve (DDV), a f u rther important step has been made in the direction of ro b u s t- ness and energy saving. his linear force motor driven pilot valve is developed as a variant of the proven Moog DDV Series. he integrated electronics of the D68 series is also a new development featuring SMD technology, and re q u i res 24 V DC power supply. he valve series described in this catalog have successfully passed EMC tests re q u i red by EC Directive. lease refer to the respective re f e rences in the Electronics Section. N O I C E e f o re installation of the valve into the system, the complete hydraulic system must be flushed (according to ISO 672). lease read the notes in section entitled Electronics, page 6.

ENEFIS ND FUNCIONLI D 6 8 1 - D 6 8 5 O E R IONL FEURES OF HE DIREC DRIVE ILO V LVE direct drive pilot valve re q u i res no pilot leakage flow. his results in considerable energy savings, especially for systems with multiple valves. he dynamics of the direct drive valve is nearly independent of the operating pre s s u re. Reliable operation. he excellent pre s s u re gain of the pilot valve with spool / bushing, provides high spool driving forc e s to the long stroke main spool. his ensures enhanced main spool position control even with high flow forces and contaminated fluids. Excellent dynamics based on a high natural frequency allows high main spool position loop gain, resulting in extre m e l y good static and dynamic response of the main valve. O E R IONL FEURES OF HE COMLEE V LVE Valve body for high rated flow, optional with external pilot supply using and port s. Reduced spool drive area with D683 and D684 Series re s u l t s in the following advantages: - i m p roved dynamic re s p o n s e - reduction in pilot fluid flow for fast movements of the main spool. Failsafe versions available with defined safe spool position using a spring and a 4/2-way solenoid valve for control flow s h o rt circ u i t. he D68 series pro p o rtional control valves are of two-stage d e s i g n. y combining a fast first stage, suitable main spool drive are a and integrated electronics, an optimum pro p o rtional valve can be off e re d. DESCRIION OF HE DIREC DRIVE ILO V LV E he D633 Series pilot valve consists of a permanent magnet linear force motor, a drive rod connecting motor arm a t u re and the spool guided in a bushing. he linear force motor contains a coil, permanent magnets, pole pieces, an arm a t u re and a centering spring arr a n g e m e n t. he 4-way spool controls fluid flow from the pre s s u re port to one of the load ports, and also from the other load port to re t u rn. Deflection of the centering spring due to spool displacement, provides a re t u rn force for the arm a t u re. n electric current applied to the coil of the linear force motor p roduces an electromagnetic flux depending on the curre n t p o l a r i t y. his electromagnetic flux is superimposed on the permanent magnetic flux in the airgaps between arm a t u re and pole pieces. his results in a polarity dependent displacement of the arm a t u re against the centering spring force. he spool being connected to the arm a t u re by a rod shares the a rm a t u re motion. Flow forces acting on the spool due to the fluid flow through the valve, and friction forces between spool and bushing due to contaminated fluid, are overcome by the f o rce motor. he position of the spool is approximately prop o rtional to the coil curre n t. O E R ING RINCILE OF HE COMLEE V LVE he position control loop for the main stage spool, position transducer and pilot valve is closed by the integrated electro - n i c s. n electric command signal (flow rate set point) is applied to the integrated position controller which drives the current in the pilot valve coil. he position transducer (LVD) which is excited via an oscillat o r, measures the position of the main spool (actual value, position voltage). his signal is then demodulated and fed back to the controller where it is compared with the command signal. he controller drives the pilot valve until the error between command signal and feedback signal is zero. hus, the position of the main spool is pro p o rtional to the electric command signal.

VLVE ELECRONICS D681-D685 VLVES FOR LICIONS WIH SFE REQUIREMENS (FILSFE) WIH 11+E CONNECOR For applications with proportional control valves where certain safety regulations are applicable, a safe metering spool position is needed in order to avoid potential damage. herefore, a failsafe version is offered as an option for the multi-stage Moog roportional Control Valves. fter switching off the 24 V supply to the safety solenoid valve, this failsafe function causes a safe metering spool position, overlapped centered position or fully opened or. In order to move the spool to the safe centered position with D68 Series failsafe valves, the two control chambers of the main stage are hydraulically short circuited via a 4/2-way solenoid valve. he spring force moves the spool into the overlapped centered position. In order to reach the fully opened position with D68 Series failsafe valves, the spring force (after the control chambers have been short circuited) pushes the spool to the end position or. With failsafe valves, it is possible to check whether the main spool is in safe position. If the main spool is within the defined safe range, the logic output signal at pin 11 is > + 8.5 V. If this signal is < + 6.5 V, then the main spool is outside the safe range. his logic signal may be delayed up to 5 ms. o reduce the failsafe switching time, it is advised to both switch off the supply of the 4/2-way valve and the enable signal at the same time. NOE: ccording to DIN-EN 954-1, a higher safety category can be achieved if a failsafe valve is used. ELECRIC CHRCERISICS 4/2-way solenoid valve for the failsafe version.
