CE certificated 220Vac 2 Way High Quality Brass Material Motorized Zone Valve HTW-V71

Product ID : HTW-V71

Product Tags : Motorized Zone Valve

Product Attributes :

HTW-V71 Series Motorized Valves are used to control the flow of hot water, chill water through the fan coil unit in heating,
cooling or air-conditioning applications, so as to control room temperature indirectly. When thermostat sends the controlling signal to the motorized valve, the valve is opened with water flowing, and when the signal disappears, the valve, with the help of its own spring, returns back to its original place to close the valve so as to stop the water flow.
