50mm Weld or Clamp on Blow Off Valve
This valve currently has the largest bore and flow rate of all the valves we produce. The internal diameter of the inlet port is a massive 50mm diameter. It is very responsive with 100% full flow to atmosphere having no restrictions at the outlets. The Banjo style top port will accommodate 360 degree positioning of the vacuum hose. Internally the valve uses a Single alloy billet piston combined with our current range of valve springs. This enables the valve to be tuned to suit your boost level. The base of the body is threaded to accept the valve mounting tube which is supplied with the other end machined to ease welding to round pipe.
Matching Springs to Boost Pressure The following is a guide for matching to spring needed to the boost pressure. With the boost spikes that are often present, we have adjusted the values to give a safe working pressure, as in reality all the springs held slightly more than these pressures.
