NACHI(FUJIKOSHI) Hydraulic Manual Selector Valves
A hydraulic manual switching valve is a type of hydraulic valve that is a directional control valve that manually switches the direction of oil flow. Used for spool-type hydraulic valves, the position of the spool is switched by operating a lever. The skewer-shaped spool moves in the axial direction to open and close the throttle and control the flow. It can be operated with little force, and easily handwheel operation at high pressure. Products that utilize the rotary method by switching the flow by rotating the spool are also available. Some products have a detent mechanism that prevents switching of the valve due to vibration or impact, and others have a structure that maintains the pressure balance to reduce the change in handwheel operation force caused by a change in pressure. The gauge cock is used to temporarily shut off the fluid when attaching and detaching the pressure gauge.
