Heating valve for greenhouses

WV3 Heat Valve

Reliable 3-way regulating valve for hot water systems

The DGT by Senmatic WV3 heat valve is a 3-way regulating valve for controlling hot water heating systems. WV3 is made to meet the special requirements of heat regulation in greenhouses and with special emphasis on reliability.

WV3 has a reliable electric motor which can be supplied with connection for 24 or 220/240 V. The end-stop is designed in such a way that it also functions as overload protector. This means that breakdowns can be avoided in case the cone is jammed by foreign bodies in the water, for example iron scales. If the power fails, the valve can be controlled by a simple manual operation.

Supplied as threaded or flanged valves
WV3 can be supplied in standard sizes as threaded valves with dimensions 15, 20, 25, 32, 40 and 50 mm, and flanged valves with dimensions 32, 40, 50, 65, 80, 100, 125 and 150 mm. All counter flanges conform to DIN 2633.
