Description
This spring-loaded, dual-acting pressure and vacuum relief vent provides much needed protection from dangerous build-up of positive and negative forces, knownas pressure and vacuum, on tank trailers transporting hazardous chemicals. Each vent is carefully assembled andtested to each customers’ exact specifications. Careful attention was paid to the design around theidea of a minimization of repair parts and a vent which could be easily disassembled with simple hand tools. Our patented design can be disassembled using our pressure spring “caging” disassembly feature. This feature effectively “traps” the spring and reduces the internal pressure enough to allow easy
separation of the valve housings. The main wearable parts are exposed, facilitating cleaning and repair. The vent can be returned to service within minutes.
