SKU# 17523-01

The 3-Port Pilot Valve (SKU: 17523-01) by the Watson Chalin is a push/pull solenoid valve that helps control the drop axles. This products’ intended use is for the control of the drop axle(s) from the suspension systems and has a 3-port structure. This push/pull solenoid part operates by an on/off actuator that generates force in one direction when the solenoid is energized. In return, the force moving in the opposite direction must be generated externally to a spring. The solenoid valve becomes electromagnetic and can act on the spring pressure to cause the spool to rotate the coil which creates the operations to control the drop axles.
