An electro-hydraulic proportional relief valve designed to regulate pressure in a hydraulic system in proportion to an applied electrical input. These open-loop, single-stage valves can be used for direct control of pressure in low flow systems, or for pilot control of larger pressure controls, and for such applications as pressurecontrolled pumps.
The integral amplifier allows the pressure to be controlled from a low power command signal: either a voltage or current command. The amplifier is mounted in a robust metal housing and electrical connections are via an industry standard 7-pin plug. Factory-set adjustments ensure high reproducibility valve-to-valve.
Other Models For proportional pressure relief valves with flow ratings up to 400 L/min (106 USgpm), see catalog V-VLPO-MC003-E (model types KBCG, sizes 6 and 8).
Features and Benefits
Valve design ensures low hysteresis and good repeatability.
Self-bleeding design simplifies installation and ensures consistent performance.
When used for piloting a large pressure relief or reducing valve, a low minimum pressure is obtainable, combined with fast and stable response to step input signals.
