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.
