Sandwich Valves Technical Information Series PRDM General
Catalog HY14-2500/US Technical Information Sandwich Valves Series PRDM General Description B Series PRDM are direct operated pressure reducing valves that are used to regulate pressure in one area of a hydraulic circuit at a predetermined level below normal system pressure. Additionally, an integral pressure relieving function for the secondary reduced pressure circuit is incorporated into the design. Operation These valves are “normally open” devices that allow fluid to flow through the controlled port during their non-actuated or “at rest” condition. When downstream pressure exceeds the value set by the spring force, the control piston moves off its seat, closing off the flow path and thus reducing the fluid passing through from the main system. The cushioned piston modulates to maintain the preset pressure in this branch of the hydraulic circuit. If, due to external forces, the pressure continues to rise in this branch circuit, the piston will keep moving against the spring force allowing fluid to be drained to tank, thereby limiting maximum pressure to the valve’s setting.

Fluorocarbon seals are available. Pressure Range PRDM sandwich valves may be selected to reduce pressure in the 'P' port, 'A' port or 'B' port. The direct operated, cushioned piston design results in fast response, low leakage and minimal hysteresis. Up to nine pressure adjustment ranges are available with maximum pressure settings. Available gage port connections include SAE, NPT, Metric and BSPP.

This style valve is well suited to perform this function as it mounts directly below the directional control valve. B 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. Features s s s PRM sandwich style pressure reducing valves can be used to reduce pressure on the 'P' port, the 'A' port, or the 'B' port. Three pressure adjustment options are available: slotted screw, 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.

Remote Control Remote control valve connected to the vent port can be used to control the pressure.2 Drain Line Drain line from pilot valve is internally connected to the tank port. Tank line pressure is thus added to the valve setting.3 1 Change in flow, temperature or fluid (SSU) rating will affect valve minimum pressure. 2 Set main valve pressure 10 Bar (150 PSI) higher than remote pilot. 3 It is important that the drain line connection be taken into consideration when determining the minimum valve setting.
