Description
>>General
HTW-DH Series Motorized Ball Valves are used to control the on/off of heat/cool water air-conditioning system pipe to control the room temperature. The valve is driven by synchronous motor. The motor connects with room thermostats by the terminal of common, open and close. By sampling and dealing with the site data, the thermostats send control signal to open/close the motor of ball valve. Then the heat/cool water enters into fan coil unit to supply the heat or cool air. When the room temperature reaches the set-point, thermostat will send a signal to cut off the ball valve and make it on the best status. Then the room temperature will keep in the comfortable range.
Valve thread size: G1/2,G3/4,G1,G1.1/4
Thread connection. Valve body could be installed first. Simple wiring. The actuator could be installed near to the wall.>>Technical Parameters
