General Description
Direct Acting Poppet-Type Relief Valve.
For additional information see
Technical Tips on pages PC1-PC6.
Features
•
Hardened, precision ground parts for durability
•
Internal mechanical stop limits poppet travel eliminating
spring solidification
•
Spherical poppets for low leakage
•
“D”-Ring eliminates backup rings
•
All external parts have yellow zinc dichromate. This
coating is ideal for salt spray applications.
