DESCRIPTION
A cartridge valve designed to combine a shock relief valve, (direct acting)
and anti-cavitation function through the check valve.
OPERATION
The RV-080 prevents flow from ¡ to ¿ until the set crack pressure at ¡ is
achieved. The poppet then unseats allowing flow from ¡ to ¿, protecting
the circuit from over pressurization.
The RV-080 allows free flow from ¿ to ¡. As pressure at ¿ exceeds
pressure at ¡, the valve unseats from the cavity allowing flow from ¿ to
¡. This provides anti-cavitation function through the check valve.
FEATURES and BENEFITS
Rapid response to pressure surges.
Anticavitation function through the check valve.
Hardened precision poppet and seat for long life.
Fast opening and closing.
Low hysteresis.
Compact size.
