22MM Motorised Zone Valve Three Way Ball Valve For HVAC Central Heating System
3 way motorized zone valve, heating control valves for HVAC, heating system
Product Description
The zone control valves use electricity to direct the water in central heating systems from the boiler to where it needs to be - either to the cylinder coil to heat the hot water, or to your heating circuit to heat (typically) your radiators. Our range consists: diameters ranges DN10-DN32, 2 and 3 ports, both end threads: female, male, or female-male, they are widely used in central heating systems to control the flow of heated water in the home.
