Cooling valve REKV 20

Area of use

The REKV 20, together with a control device, can be used in cooling plants to regulate primary or secondary flow on cooling ceilings, refrigerated display cases, refrigerating chambers, fan coils etc.
The REKV 20 can be regulated with the capillary tube thermostat or with an electronic thermostat via an actuator.

Description

The valve can be pre-set between kv 0.4 – 2.5.
With a self-acting thermostat mounted, the valve opens when the temperature at the sensor rises, and closes when it lowers. The valve is manufactured in dezincification resistance brass.
The valve is supplied with a protective cap in grey, which denotes pre-setting.The protective cap may during installation be used as shut-off, and also during pre-setting to set nominal opening with thermostatic head mounted. Turn the cap to the bottom and open 3/4 turns.
