This valve consists of a small DC solenoid and a direct-acting relief valve. It serves as a pilot valve for a low flow rate hydraulic system or a proportional electro-hydraulic control valve and controls the pressure in proportion to the input current. Note that this valve is used in conjunction with the applicable power amplifier.
Instructions：
1. Tank-line Back Pressure．Check that the tank line back pressure does not exceed 0.2MPa
2. Vent Control．When the valve is used for vent control of relief valves or others, use the pipes of 6mm, ID.300mm or less length for connection.
3. Circuit Pressure Control．When the pressure in a circuit is directly controlled with this valve, set the trapped oil volume being more than 40cm³.
4. Safety Valve Pressure Setting．The pressure of the safety valve at the maximum flow is preset at the value equal to the upper limit of the pressure adjustment range plus 2MPa.In case where the upper limit of operating pressure is low or the upper limit of flow rate to be used is different from the specified maximum flow, please adjust and determine the setting pressure of the safety valve at the value calculated from the following formula.
Setting pressure = (Operating pressure upper limit)+(Additional pressure indicated below)
To lower the setting pressure, turn the safety valve pressure adjustment screw anti-clockwise. After adjustment, be sure to tighten the lock nut．
