Brass Three way valve Thermostatic Radiator Valve for heating system T type temperature controller valve DN15 DN20 DN25 DN32Product's detials:Material:brass CW617N body,EPDM Seal Material:Pressure: PN <1.6MpaWorking medium: water, charge corrosive liquidTemperature: minus 20 degrees to 110 degreesThread: M30X1.5Easy to be installedNote: DN15(1/2"-Inch),DN20(3/4" inch),DN25(1" inch),DN32(1-1/4"),Description:Thermostatic radiator valve in this design is the self-adjustable control valve without needs of external energy , it can be adjusted independently for temperature in each room. And thereby maintaining a constant room temperature required. It features energy-saving and easy to use and so on.The working principle of this design of valve is: the liquid temperature sensing element thermostatic valve head is to feel the room air temperature , and thereby changing the heating water flow , so as to regulate and control room temperature :i.e., when the indoor temperature rises , the thermal expansion of the temperature sensing material shall compress to the valve stem to close down the valve up to shut up ,and on the contrary ,the stem shall rebound to open up the valve. In this way, a more comfortable temperature environment for people is achieved.Meanwhile, if there is other auxiliary heat source(such as sunshine or other heater etc) in the room, the valve shall close down a little to reduce the water flow into the radiator, and achieve the target of energy-saving in the end.Other Related product links are as belowing:
