Flow Control Valves
Pilot Operated Flow Control Valve (FH(C)G) Series
Flow control of these valves is continuously made by a hydraulically operated pilot piston mechanism which controls opening area of the orifice of the valve. With the use of these valves, Shockless operation either in acceleration or deceleration can be obtained. With the compensator for the pressure and temperature, stable flow control can be obtained regardless of the changes in the pressure (load) and temperature (oil viscosity).
Deceleration & Check Valves (Z(C)T)
These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their principal use is to control the speed of actuators in machine tools and similar applications.
Flow Control and Relief Valves (FBG-03/06/10)
These valves are flow control valves having the functions of meter-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 present 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 the 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.
