This is a 3-way auto-reset valve, essential for controlling fluid flow in pneumatic or hydraulic systems on heavy-duty trucks. It automatically returns to a default position when pressure is released, ensuring system safety and proper function. This valve is constructed from durable materials to withstand the demanding conditions of commercial vehicle operation, differing from a worn valve that may stick or leak. Symptoms of a failing valve include unintended system actuation, slow response times, or a complete loss of control over the connected system.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a faulty valve is inconsistent or delayed response in the controlled system. If ignored, the valve may fail to reset, leading to the system remaining in an unintended state. This can result in compromised braking performance or loss of control over critical functions.
Ensure all air lines are properly connected and secured to prevent leaks, which can affect the valve's auto-reset function. Avoid overtightening fittings, as this can damage the valve body.
Inspect associated air lines and solenoids for damage or wear when replacing this valve.
