Neptune RV-C20-1 Relief Valve

Relief Valves

Neptune's Relief Valves protect the piping and system from overpressure. If released, the relief valve discharge is piped to a tank in order to prevent any system or piping damage. Neptune's exclusive relief valve design utilizes a unique spring guide which assures proper spring loading and consistent relief capacity. The relief pressure setting can easily be changed by removing the top cap screw and locking set screw, inserting a proper allen wrench into the opening and adjusting the sprint to the desired pressure. Additionally, Neptune's relief valves use a self-cleaning ball check and seat.

Neptune Relief Valves have two outstanding characteristics:

Economy. Models RV-316-1, -2, -3 and -4 with all 316SS wetted parts cost no more than other 304SS designs. C-20 valves are also available as standard.

Simplicity. Neptune exclusive design uses a self-cleaning ball check and seat. It has a unique spring guide which assures proper spring loading and consistent relief capacity. The relief pressure setting can be easily changed by removing the top cap screw and locking set screw, inserting a proper Allen wrench into the opening, and adjusting the spring to the desired pressure.

Recommended setting: Operating pressure plus 10% or 50 psi whichever is greater.
