The PRV9i range is manufactured using marine friendly alloys to suit the harshest of environments. The inner working parts of PRV9i are manufactured in aluminium bronze as standard, while body castings are typically cast in gunmetal. Body castings can also be manufactured in aluminium bronze if required.
PRV9i valves are all manufactured in our UK based factory in Yorkshire. The design, casting, machining and assembly plus full flow testing and calibration are all assessed to the current ISO 9001 standards. Full certification and testing is available if required.
