KCG3 Proportional Pressure Relief Valves

The KCG3 is a 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 pressure controlled 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.
