We can supply different size of TRVs including DN15 (Nominal
diameter), DN20, DN25. Straight valves, angle valves, three way
valves, three way cross valves are all in our product line.
For customers convenience, we also provide valves with PPR
We can also make valves according your requirement or samples.
3. Features and Function
a. Wax sensor provides consistent and reliable performance.
b. Provide individual room temperature control by varying the
flow of water through the radiator.
c. The valve body is made of non corrosive nickel-plated
4. Whatre the thermostatic radiator valves?
Thermostatic radiator valves (TRVs) sense the air temperature
around them. They work by regulating the flow of water through the
radiator which they are fitted to. However, it is important to
remember that they do not control the boiler. TRVs are beneficial
in providing much more focused control within a room. Therefore,
you can set each TRV to a temperature best suited to each room.
This is greatly beneficial in saving energy, as it offers the user
the flexibility to have varying temperatures in separate parts of
the home, rather than wasting energy heating a room that may not be
They are provided with a regulating element which automatically
controls the opening of the valve to keep ambient temperature of
the room where they are installed constant at the set value. The
number on the valve corresponds to a specific air temperature. Once
you have selected a number, the thermostatic valve will maintain
this temperature. This prevents unwanted temperature rises and
achieves considerable savings.
5. Precaution for Use
a. TRVs sense the air temperature around them and regulate
the flow of water through the radiator which they are fitted to.
They do not control the boiler.
b. These settings may have to be different in each room, and
you should set the TRV s to suit each room and then leave them to
do their job.
c. Turning a TRV to a higher setting will not make the room
heat up any faster.
How quickly the room heats up depends on the boiler size and
setting, and the radiator size. Turning a TRV to a lower setting
will result in the room being controlled at a lower temperature,
and saves energy
d. TRVs need a free flow of air to sense the temperature, so
they need a free flow of air to sense the temperature. They should
not be covered by curtains or blocked by furniture. Nearby
sources of heat such as lamps could also stop them from working
e. In Summer, ensure you leave all your TRV valves in the
FULLY OPEN position, that is, at the highest number, to avoid
sticking in the closed position, when you will need them open in
WINTER! Since your ROOM THERMOSTAT will be set lower than the
ambient temperature, this will NOT be a problem in the hot summer
f. If fitting new TRVs, dont throw away the plastic
caps that come with them, put them in a safe place. Unless your
valves come with an OFF position, you will need those to screw on
to the valve, to force it into the OFF position, if removing the
radiator (the thermostatic part is held on with a screwed collar,
and will need to be removed to fit the plastic shut-off cap on the
valve, in its place). You may otherwise find that the minimum, or
FROST position does not completely stop the water flow.
