A screw-in, cartridge-style, bypass-type, pressure-compensating element, with
integral flow regulator for load sense signal drain. The internal pressure-compensated
flow regulator restricts the load signal bleed flow in order to minimize system losses
even at high operating pressures. The main compensator element holds the valves
primary flow constant regardless of load pressure changes.
The EPFR58-35 is a spring-biased spool-type valve with an internal pressure-compensated
flow regulator between 2 and 3. When used as a pump unloading compensator, this valve will
bypass flow to tank at port 2 when system pressure reaches the load pressure plus the bias
spring value. When the system load is neutralized, the load signal is bled through the flow
regulator bringing the valve to stand-by condition.
• Multiple function in a single cavity.
• Low bleed flow throughout the operating pressure range.
• High system efficiency.
• Industry-common cavity.
