The Shut Off 150 P.S.I Max is a brass shut-off drain valve designed for high pressure air/fluid systems used in commercial vehicles (trucks, trailers, and construction equipment) for quick draining, contaminant venting, and system isolation in brake systems, tanks, or hydraulic lines. With a maximum working pressure of 150 PSI (10.3 bar), they are designed for more demanding applications.air/liquid systems. It is mainly used in the braking system, air storage tank, or hydraulic pipeline of commercial vehicles (trucks, trailers, construction machinery) to achieve rapid drainage, impurity discharge, and system isolation functions. Its maximum working pressure reaches 150 PSI (10.3 bar), suitable for more demanding working conditions.

 

 

High-pressure Shutoff And Drain:

Completely shuts off lines and isolates air/fluid lines for easy maintenance (e.g., no need to drain the entire system when replacing parts).

Quickly drains condensate, oil, and solid particles from the reservoir when the valve is turned on, preventing brake system corrosion or winter icing.

 

Double Sealing Guarantee:

Metal-to-metal taper seal: High pressure resistant, vibration resistant, not easy to fail in long term use.

FKM O-ring: Oil and high temperature resistant, maintains elasticity under extreme working conditions.

 

Safety and Convenience Design:

Anti-misoperation knob: Requires a certain torque to open, avoiding accidental opening resulting in pressure leakage.

Large-size operating head: Can be easily screwed even with gloves, suitable for outdoor or low temperature environments.

 

Long Life & Low Maintenance:

Brass material resists corrosion and supports 20,000+ cycles of opening and closing.

Maintenance requires only cleaning the sealing surfaces, not replacing the entire valve body.
