VSD*M-VPD*M - PILOT OPERATED DIRECTIONAL VALVES PILOT OPERATED DIRECTIONAL VALVES The VSD*M and VPD*M pilot operated directional control valves are available with either electric solenoid or hydraulic actuation of the main spool. Available in 5 standard NFPA and ISO patterns, these pilot operated valves are used in applications requiring high flow rates. The valves are available in both 2 or 3 position and various spool flow patterns. On VSD*M valves, the configuration for internal or external pilot/drains can be easily changed in the field. Also available to improve consistent cycling of...

MECHANICAL OPTIONS VSD*M-VPD*M - PILOT OPERATED DIRECTIONAL VALVES STROKE ADJUSTMENT (JJ) This modification controls the flow of oil through the valve by limiting spool movement. It is used in hydraulic systems to govern the speed of system components. This solution allows control of the flow rate from the pump to the actuator and from the actuator to the outlet, obtaining a double adjustable control on the actuator. It is possible to order the valve with the stroke adj. on one side only. To request these options add the letters JA or JB in the Mechanical options box in the identification...

PILOT AND DRAIN CONFIGURATION The VPD*M valves are available with external pilot and drain only. The VSD*M valves are available with four pilot/drain configurations: internal/internal, internal/external, external/internal and external/external. It may be desirable to use external pilot when system pressure is subject to wide flucuations. It is required to use external pilot or internal pilot with a pressure reducing valve when system pressure exceeds 3000 psi (210 bar) for the VSD05*M, VSD07M and VSD10M. An external drain must be used when an open center (B) or a tandem center (L) spool is...
