Electro-Hydraulic Flow Control and Relief Valves
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
powerconsumption 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.
Drain Back Pressure:
Check that the drain
back pressure dose not exceed 0.2 MPa (29 PSI). When Relief Valve Passing.
Flow Rate is Low in
Pressure Control State:
To avoid preselected
pressure instability, use a passing flow rate of 15 L/min (4.0 U.S.GPM) or
higher. Further, check that the tank-line back pressure dose not exceed 0.5 MPa
Safety Valve Pressure
The pressure of the saffety valve is preset at the value
equal to the upper limit of the pressure adjustment renge plus 2 MPa (290 PSI).
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
