What We Do

Fire protection for the brave men and women who protect and serve.

PRPV Industries’ pneumatic release pilot valve is an integral part of shipboard magazine fire protection. Our enduring design has been protecting our fleet for the past 70 years.



The PRPV is a normally closed spring-loaded pilot valve that opens automatically to actuate the magazine sprinkler system in response to a pneumatic signal from one or more thermopneumatic elements.



The three main components include the operating mechanism, the compensating vent, and the pilot valve. The valve assembly is provided with shock mounts and brackets for fastening to a bulkhead.



PRPV is equipped with a compensating vent which bleeds off the slight increase or decrease of pressure caused by normal fluctuations in temperature. This prevents an inadvertent tripping of the valve.
