EVM / CV, pilot valves/valve body for Pressure and Temperature Regulators The range of pilot valves consists of: Constant-pressure pilot valve, type CVP (LP) and CVP (HP). Differential-pressure pilot valve, type CVPP (LP) and CVPP (HP). High pressure pilot valve, type CVP (XP), ideal for CO2 hot gas defrosting. Pressure-operated pilot valve with reference pressure connection, type CVC. Electronically operated constant-pressure pilot valve, type CVQ (pressure-dependent).
Solenoid pilot valve, type EVM (NC). Solenoid pilot valve, type EVM (NO). Housing, type CVH for pilot valves, for mounting in external pilot lines. Applicable to all common non flammable refrigerants including R 717 and non corrosive gases/liquids dependent on sealing material compatability.  
The pilot valves can be screwed direct into the main valve, thus avoiding the necessity of welding, soldering and separate pilot lines.
The pilot valves can be mounted direct in a ICS or PM main valve or be connected via an external pilot line and a CVH housing.
All pilot valves can be used on all sizes of main valves.
Extremely accurate pressure and temperature control.
Several pilot valves can be connected in series or in parallel to provide many functions in the same ICS or PM main valve.
All pilot valves are delivered with gaskets.
