10Ω-10Ω Series Proportional Electro-Hydraulic Flow Control and Relief Valves,E Series

　　This flow control and relief valve is an energy-saving valve that supplies the minimum pressure and flow necessary for actuator drive.

　　Since this valve controls the pump pressure by following the load pressure while keeping the differential pressure minimized, it serves as a low power-consumption energy-saving, metre-in, controlled flow control valve. Further, since a temperature compensation function is incorporated, this valve provides consistent flow control without respect to the fluid temperature.

　　Instructions：　　

　　1. Drain Back Pressure —— Check that the drain back pressure does not exceed 0.2MPa.

　　2. When Relief Valve Passing Flow Rate is Low in Pressure Control State.To avoid preselected pressure instability, use a passing flow rate of 15L/min or higher. Further, check that the tank-line back pressure does not exceed 0.5MPa.

　　3. Safety Valve Pressure Setting ——The pressure of the saffety valve is preset at the value equal to the upper limit of the pressure adjustment range pluse 2MPa. Please adjust the pressure of the valve so preset to meet the pressure to be used actually. To lower the pressure setting, turn the safety valve pressure adjustment screw anti-clockwise. After adjustment, be sure to tighten the lock nut.
