4SH Series Pilot Valve
Application
This series of pilot valves is mainly used for the control oil line of a hydraulic system and enable control oil with low flow and pressure to control the output pressure of pilot oil so as to meet the requirement on working conditions of the system. The product can be adopted to control multiway valves and be widely applied to engineering machines like excavator, loader and heading machine.
