Cooling valve EKV

Area of use

The EKV together with a control device, can be used in cooling plants to regulate primary or seccondary flow on cooling ceilings, refrigerated display cases, refrigerating chambers, fan coils etc.
The valves can be used with a self-acting thermostat or electronic thermostat via an actuator.

Description

The valve opens when the temperatur near the thermostat or actuator raises and when the temperature drops it closes the valve. The valve is made in dezincification resistance brass.The valve is supplied with a protective cap in yellow, which denotes no 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. EKV 15 special is made for higher water pressuredrop max closingpressure is 8 bar = 800 kPa
