General Description
Direct Acting Pressure Reducing/
Relieving Valve. For additional
information see Technical Tips on
pages PC1-PC6.
Note: The differential between system
pressure and pressure setting of the valve can greatly
affect the stability of this valve. For best performance,
the inlet pressure setting should not exceed 69 Bar
(1000 PSI) above the reducing valve setting.
Features
•
Hardened, precision ground parts for durability
•
Internal mechanical stop limits spool travel eliminating
spring solidification
•
“D”-Ring eliminates backup rings
•
All external parts have yellow zinc dichromate. This
coating is ideal for salt spray applications.
