Product Description

SPDT/SPST Wiring Type Motorzied Brass Valve for HVAC 

>> 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(SPDT) or connects with only normally open

terminal from thermostat(SPST). 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,G1.1/2 (G=BSP=BSPP, NPT optional) Thread connection. Valve body could be installed first. Simple wiring. The actuator could be installed near to the wall.
