Product Description

Brass Material Valve Motorized Valve Water Flow Control

>> General                                                      

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.

>>Installation  Instruction                               
1.Dimensions Diagrams, Pleasse refer to fig 1
2.The valves can be mounted in horizontal or vertical piping, When installed in horizontal piping, the actuator must be above the valve body, and it can be titled left or right but it must NOT be below 85 degrees from vertical. Please refer to Fig 2.
3.If the valve as mounted in vertical piping, please be sure the cover of motor is waterproof.
4.When installing the actuator to a normally closed valve, the actuator must be placed in the manually open position by using the manual operating lever. The first time the valve operated electrically, the manual operating lever of the actuator will transfer to the automatic poison.
