CVP is a constant-pressure pilot valve available in low-pressure and high-pressure versions. The pilot valve is used to maintain a constant pressure on the ICS or PM main valve inlet side.
The low-pressure version (LP) must not be subjected to pulsation.
CVP (XP) is a constant-pressure pilot valve available in high-pressure version. The CVP (XP) ensures an efficient and stable CO2 hot gas defrost process.
When a CVP is mounted in a CVH housing, it can be used as a separate constant-pressure valve or a pressure relief valve (e.g. to prevent hydraulic overpressure in an entrapped liquid).
