The AMETEK Vehicle PRV is specifically designed for Military applications, being suitably balanced and damped to compensate for vehicle movements: This feature allows better control of vehicle overpressure than other types, which can suffer from pressure fluctuations. The Vehicle PRV is not sensitive to attitude and can be mounted on vertically or horizontal surfaces
The PRV is in current service in a range of wheeled and tracked Military vehicles.
A simpler design of PRV is also available, which is a lower cost solution, but this does not include any form of compensation for vehicle movement and should only be installed on a vertical surface – unlike the Vehicle PRV above
