Pentair Anderson Greenwood pilot operated pressure relief valves provide advanced, reliable and efficient overpressure protection. With a track record of more 50 years, the product technology is designed for a wide range of applications, from basic to the most severe service conditions.
Because the POPRV does not use a spring to hold the main valve seat closed, considerable height savings are achieved in the valve design. The same pilot valve is used for all main valve sizes providing significant height savings particularly on larger and higher pressure valves. This enables the POPRVs to be used in applications where space is at a premium.
