Pressure Reducing Sandwich Valves

Series PRM

General Description:

Series PRM reducing valves are used to regulate pressure in one area of a circuit below normal system pressure. This style valve is well suited to perform this function as it mounts directly below the directional control valve.

Operation:

These are "normally open" valves that allow fluid to pass through the controlled port during typical operation. When downstream pressure rises above the value set by an adjustable spring force, the control pilot opens and allows the main spool to move from a full open position. The main spool modulates to maintain the desired "reduced pressure" downstream of the valve. The PRM3 also has a relieving mode.

Series ZDR

General Description:

Series ZDR pilot operated pressure reducing valves are designed for maximum flow rates.
The reducing function can be located in the ports P, A or B. The sizes NG06 and NG10 are equipped with an integral return flow check valve (reducing function in A or B).

Series PRM

Features:

  • PRM sandwich style pressure reducing valves allow for easy configuration of stack systems and can be used to reduce pressure on the 'P' port, the 'A' port, or the 'B' port.
  • Four pressure adjustment options are available: slotted screw, hexagon socket screw (PRM4), knob and locking knob. (PRM6 only)
  • Valve bodies are manufactured from steel which provide extra strength and durability for longer life. Internal hardened steel components also provide longer life
