Blow Off Valves

A blowoff valve is connected by a vacuum hose to the intake manifold after the throttle plate. When the throttle is closed, the relative manifold pressure drops below atmospheric pressure and the resulting pressure differential operates the blowoff valve’s piston. The excess pressure from the turbocharger is then vented into the atmosphere or recirculated into the intake upstream of the compressor inlet. Blow off valves are also commonly known as deverter valves, recip valves or reciprocating valves. If you’d like help finding the right option for you, contact us today! [email protected]
