Hydraulic Pilot Valves for Joystick & Foot Pedal
Precision joystick and foot pedal pilot control systems designed for smooth, reliable remote operation in mobile and industrial hydraulic applications.
Product Overview
Pilot control devices are primarily used to control proportional directional valves and hydraulic pumps. In terms of control methods, they can be operated manually (including foot-operated) or electronically. In addition to conventional pilot control devices that use hydraulic fluid as the working medium, we also offer pilot control devices that use gas as the working medium.
Working Principle
Pilot control device joystick and foot pedal work according to the principle of direct-acting pressure reducing valves. In rest position, the joystick lever or kit pedal is held in neutral by return spring; inlet port P is closed and service ports (1 – 2 – 3 -4) are connected to tank port T. By selecting control lever, plunger compresses return spring and reaction spring through cam mechanism; It shifts spool and opens connection holes between inlet port P and service ports consequently. This causes a pressure increase on service ports that is proportional to the control lever stroke and the reaction spring.
