Relief Valves

Features

• All wetted parts are 316SS or Carpenter 20

• Pressures from 30 to 2000 psi

• Spring guide for consistent relief capacity

• Easily adjustable relief setting

• Liquid service only

Neptune Relief Valves have two outstanding characteristics:

• economy • simplicity

Economy. Models RV-316-1, -2, -3 and -4 with all 316SS wetted

parts cost no more than other 304SS designs. Carpenter 20 valves

are also available as standard.

Simplicity. Neptune’s 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.
