Thermostatic Radiator Valves
Product Information:
The Thermostatic Radiator Valves are self-regulating valves
designed for domestic applications. They operate by sensing the air
temperature and controlling the opening and closing of the valve to
maintain a constant room temperature. The valves come in different
models with different connection types, package types, and
colors.
Technical Data:
- Temperature Range: 0-5 (calibration marks on the sensor
head) - Maximum Differential Pressure: 0.6 Bar
- Static Pressure: 10 Bar
- Maximum Flow Temperature: 1 M3/H
- KVS Value @ 1 Bar: Depends on the model
Product Usage Instructions:
1. Setting the temperature:
Select the desired room temperature from the calibration marks
on the sensor head. Rotate the sensor head so that the black
indicator points to the appropriate number. Allow at least one hour
for the temperature to stabilize.
2. Frost protection:
If heating is not required but there is a risk of freezing,
rotate the sensor head so that the black indicator points to the
frost protection position. The valve will remain operational,
controlled by a frost thermostat.
3. Radiator removal:
To remove a radiator, use the manual closing cap provided with
the valve. Remove the sensor head before closing the valve to avoid
water damage if the temperature falls and the valve opens
unexpectedly.
4. Summer operation:
In summer, set the valves to the fully open position (position
5). Note that the speed at which your room heats up depends on your
boiler size and setting. Store the manual closing cap in a safe
place for future use.
Installation Instructions:
1. Fit the manual closing cap and screw it clockwise to close
the valve. Do not over-tighten.
2. Apply PTFE tape to the 1/2 BSP tail and screw it into the
radiator.
3. Connect the valve body by sliding the nut and olive onto the
tail. Apply a jointing compound to ensure a secure connection.
Note: Please refer to the user manual for more detailed
instructions and safety precautions.

Description
Thermostatic Radiator Valves are self-regulating valves and operate by sensing the air temperature around them. to the radiator. You should set the Thermostatic Radiator Valves to suit each room for a desired temperature. The sensor head contains a temperature sensor which controls the opening and closing of the valve thereby keeping the room at a constant temperature.

2. Frost protection
If heating is not required but there is a risk of freezing, the sensor head may be rotated so that the black
indicator points to*. This will allow the valve to open if the temperature falls below 7°C. The boiler must
remain operational, controlled by a frost thermostat.
3. Radiator removal
To remove a radiator it is necessary to use the manual closing cap supplied with the valve. Remove the sensor to close the valve there is a risk of water damage if the temperature falls and the valve opens unexpectedly.
4. Summer operation
valves are set to the fully open position (position “5”).

Installation Options
The thermostatic radiator valve can be installed on either side of the radiator, in a vertical or horizontal position. If a lockshield valve is also used on the same radiator, install it on the opposite side of the radiator. See Figure 1.0:

1. Fit the manual closing cap and screw clockwise to close the valve. Do not over-tighten. 2. Apply PTFE tape to the 1/2″ BSP tail and screw it into the radiator. 3. Connect the valve body by sliding the nut and olive onto the tail. A jointing compound should be applied to
the olive. The valve may be used with the sensor head in the vertical or horizontal postion. Do not over-tighten. 4.
Use an appropriate reducing set for 8mm and 10mm pipe sizes. 5. Undo the valve body from the tail piece. Slide nut and olive onto the supply pipe. Apply a suitable jointing
6. Fill the system, bleed the radiator and check for leaks. After commisioning, remove the manual closing cap and store it in a safe place for future use.
7. Turn the sensor head to the fully open position (position “5”) 8. Mount the sensor head to the valve body ensuring that the indicator can be seen. Hand tighten the securing
ring – do not over-tighten or use tools.
WARNING!
The sensor head must not be shielded by any object or come in contact with direct sunlight.
accordance with good plumbing practice. Use the manual closing cap (provided) to protect the valve during installation.
