DN15 boiler zone valve stuck open, pN16 brass motorized ball valve for zone valve
Product Description
A heating zone valve is hooked directly to a thermostat. An actuator motor operated valve designed for zoning hydronic heating / cooling systems utilizing baseboard, convector and fan-coil terminal units. On a call for heat or cool, the thermostat contacts close completing the circuit to the zone valve and energizing a small motor in the zone control valve. This synchronous motor opens or closes the mini motorized ball valve. As the ball valve opens an end switch in the zone valve closes. Our control zone valves and accessories are type of motorized ball vave for controlling the flow in heating and cooling system zones.
