Directional Control Valve

Model FWH is a slide valve type of directional control valve which uses a solenoid as its control pilot. It is used to open and shut off fluid flows and to control the flow direction. The FH hydraulic operated directional control valve uses pressured fluid to force direction change so as to achieve flow on-off and direction change. Its principle and structure are basically identical to FWH electro-hydraulic valve.
