DESCRIPTION
A cartridge valve designed to combine a shock relief valve, (direct acting)
a
nd anti-cavitation function through the check valve.
OPERATION
The RV-050 prevents flow from ➁ to ➀ until the set crack pressure at ➁ is
achieved. The poppet then unseats, allowing flow from ➁ to ➀, protecting
the circuit from over pressurization.
The RV-050 allows free flow from ➀ to ➁. As pressure at ➀ exceeds
pressure at ➁, the valve unseats from the cavity, allowing flow from ➀ to
➁. 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.
