To change radiator valve

Sep 22, 2013

A thermostatic radiator valve (TRV) is an automatic regulation valve that controls the flow of hot water through heating radiators based on the temperature in the room in which it is located. The valve typically features an adjustable temperature setting that allows occupants to select a comfortable temperature in their environment and automatically adjusts the internal mechanism, thereby closing or opening it as required. Radiator systems fitted with TRVs not only deliver convenient hands-off temperature control but also make hot water systems more efficient with significant cost and CO2 emission savings. TRVs may be used on most radiators, towel dryers, or convectors and are available in off-the-shelf or custom units.
The easiest way to fix a damaged radiator valve is to either clean it or swap it out for a new one. Changing it involves turning off the water source, placing the pan under each location that you work on, draining the radiator, closing all valves that were previously opened, and finally Use the channel lock wrench to remove the small section of pipe that goes into the radiator and replace it with the new one that comes with the new radiator valve kit.

Changing a radiator valve on your car can be hard and dirty work. However, if you follow these steps carefully, there should be no problems replacing the valve.

The valve sensor consists of a metal bulb filled with a heat sensitive substance such as wax. This substance will contract and expand according to the ambient temperature it is exposed to, and it is this motion which activates the rest of the mechanism. An adjustable temperature dial dictates the time taken for the sensor bulb motion to act on the mechanism, thereby allowing for a range of ambient temperature settings to be chosen. When the bulb expansion does act on the mechanism, it opens or closes the valve spindle. In this way, the valve supplies hot water to the radiator when the temperature in the room drops below the selected value and shuts it off again once the temperature has been restored.

1、Take off the radiator cap and turn the drain valve that is at the bottom of the radiator with a wrench to drain the radiator.
2、 Find the radiator hose and take it off with a flathead screwdriver.
3、 Expose the thermostat by removing the bolts on both sides of the thermostat with a wrench.
4、 Scrape the bottom of the thermostat housing and where the housing meets the surface with a gasket scraper.
5、 Put on the new thermostat and then once in place, on both sides of the newly replaced thermostat gasket, put gasket sealer on. Put the housing over the thermostat and then tighten the bolts with a wrench.
6、 Put the upper radiator hose on the housing of the thermostat and tighten the clamp with a screwdriver. Make sure to close the radiator's drain valve by turning it clockwise with a wrench and fill the radiator with antifreeze.
7、 Put the radiator cap back on.
