Pneumatic lock valve

Product Description

The Pneumatic Lock Valve is an essential air control component used in heavy-duty trucks and industrial air systems. It is designed to control and maintain air pressure, ensuring that the pneumatic system remains stable and reliable during operation. This valve helps lock air flow in specific circuits to prevent air leakage, maintain pressure balance, and enhance the safety of braking and transmission systems.

Made from high-strength aluminum or steel, the valve features precise internal sealing and corrosion-resistant surface treatment. It can operate under high temperature, vibration, and dust conditions — ideal for use in trucks, trailers, and other pneumatic systems that require dependable air control performance.
