ER-G03-B-21

Description: Electro-Hydraulic Proportional Relief Valve

The Electro-Hydraulic Proportional Relief Valve combines a compact, high performance electro-hydraulic proportional pilot relief valve and balanced piston type relief valve to provide pressure control in proportion to input current. Through-put volume and fluid temperature fluctuation have little effect on control pressure so this valve provides open loop control of even complex pressures/forces.
