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.
*For proportional pressure relief valves with flow ratings up to 400 L/min (106 USgpm), (see model types KCG, 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.
