Danfoss Pilot valve Type CVP (Constant-pressure pilot valve)
Intended for mechanical control of a main valve
CVP is a constant-pressure pilot valve for a max. working pressure (MWP) from 52 bar (754 psig) to 65 bar (943 psig)* and with 3 setting ranges covering settings of -0.66 to 52 bar (19.5 in. Hg to 754 psig). This pilot valve is used for maintaining a constant pressure on the inlet side of the main valve.
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).
(*Only CVP-M and CVP-H are approved for MWP of 65 bar)
Features:
- Applicable to HCFC, non flammable HFC, R717 (Ammonia) and R744 (CO2). The use of Pilots with flammable hydrocarbons is not recommended
- Extremely accurate pressure and temperature control.
- The pilot valves can be screwed directly into the main valve, thus avoiding the necessity of welding, soldering and separate pilot lines.
- The pilot valves can be mounted directly in the ICS, PM or ICF valve or it can be connected via an external pilot line and a CVH housing.
- All pilot valves can be used on all sizes of main valves.
- Several pilot valves can be connected in series or in parallel to provide many functions in the same ICS or ICF valve.
- All pilot valves are delivered with gaskets.
