Model Number Designation / Specifications
Up to 25 MPa (3630 PSI), 500 L/min (132 U.S.GPM)
These valves are flow control valves having the functions of metre-in type flow control and pressure control.
Inlet pressure is always maintained 0.6 MPa (87 PSI) higher than the load pressure.
In a conventional flow control method, power consumption is wasteful since the pump pressure goes up to the preset
system pressure regardless of the load pressure. While, the power saving valves control the pump pressure by maintaining
a differential pressure as little as 0.6 MPa (87 PSI) against the load pressure, thereby, the power can be remarkably saved.
Moreover, with lthe temperature compensator, a stable flow control can be made regardless of oil temperature.
Setting and repeat setting of flow can be made easily with an adjustment knob having digital scales.
