1/2 Inch 3/4 Inch 2way 3 Way 4 Way Brass Valves Water Heating Radiator Valve Thermostatic Valve for Radiator

Item:HTW-TV02

 

 >> General                                                     

HTW-TV02-VA Thermal Valve Actuator is designed to control the open/close of the pipe of chilled/hot water for HVAC system so as to control the indoor temperature and maintain a thermal room temperature.

It is installed on the chilled/hot water pipe, and the valve is controlled to open or close via the signal send from thermostat. The thermostat sends a signal to open the thermal valve to cool/ heat the room via heat exchange from the cooling/heating media, like chilled/heating water.

2 models for options: 

HTW-TV02-VAC 

HTW-TV02-VAO

HTW-TV02-VAC fits for normally closed valve bodies HTW-TV02-VBC series 

HTW-TV02-VAO fits for normally open valve bodies HTW-TV02-VBO series

 >> Valve body                                

HTW-TV02-VB series valve body is designed for temperature control in the HVAC circumstance.

There are three port type models:

--HTW-TV02-VB*-2**2 Way Valve Body

--HTW-TV02-VB-3**3 Way Valve Body

--HTW-TV02-VB-4**4 Way Valve Body

HTW-TV02-VB*-2** 2 Way Valve Body varies from 2 types as below:

--Normally close(N.C.) HTW-TV02-VBC-2**

For the normally close type valve, actuator drives the piston to open the valve on direct way and close it on angle way.

--Normally open(N.O.) HTW-TV02-VBO-2**

For the normally open 2-way valve, actuator drives to close it. Spring is used to return the piston.

These valve bodies feature with condensed structure, reliability and convenient installation.

 >> Installation                                                      

Before the installation, please make sure the pipe is clean (no soldering scraps), so the valve piston won't be blocked, and the flow direction indicated on the valve body is correct. Actuator should be mounted above the valve body. We recommend using 3-way valve as mixing valve.

*2-way valve:

A→AB normally open or normally close

*3-way valve:

A→AB normally close B→AB normally open
