PNP Vacuum Release Valve

PNP Vacuum Release Valve

The valve will allow atmospheric air pressure into the vacuum reservoir to release the brakes on a detached vehicle. The brakes will come off, as the air pressure equalises each side of the diaphragm. Before this device is used it should be established that the vehicle in question can not roll out of control.

Safe Use

PNP have provided a useful diagram of the operation of a vacuum braking system (click for link). It is the responsibility of the operator to follow the instructions provided to ensure the installation is safe. Always test braking systems in a controlled environment before running with passengers. Braking systems must be regularly inspected and maintained to ensure effective operation. MRW accepts no liability for incorrect/poor installation and product failure - this is dealt with by us on behalf of PNP.
