6. Installation
The EMKE Multiblock Radiator Valve is designed for universal use with radiators featuring a 50mm central connection and G 1/2" connection thread. It is suitable for both wall and floor pipe connections.
6.1 Pre-installation Checks
- Ensure the heating system is turned off and depressurized.
- Verify that the pipe dimensions match the valve's φ16 connection. If your water pipe size is φ15, an adapter must be used (not included).
- Clean the connection points on the radiator and pipes.
6.2 Installation Steps
- Connect to Radiator: Attach the valve block to the radiator's central connection. Ensure the sealing rings are correctly positioned and tighten the connection nuts securely.
- Connect to Pipes: Connect the heating pipes to the valve's inlet and outlet ports. The integrated design allows for both angle and passage configurations, accommodating pipes coming from the wall or the floor.
- Thermostatic Head Placement: The thermostatic head can be mounted on either side of the valve block (right or left) depending on your installation requirements and space availability.
- Secure Connections: Use PTFE tape or appropriate sealant on threaded connections to ensure a watertight seal. Tighten all connections firmly but do not overtighten.
- System Refill and Test: Once installed, slowly refill the heating system and check for any leaks. Bleed the radiator if necessary.

7. Operation
The thermostatic head allows for precise control of your room temperature. It features 7 precise adjustment settings.
7.1 Setting the Temperature
Rotate the thermostatic head to select your desired temperature setting. The settings correspond to approximate room temperatures as follows:
| Setting | Approximate Temperature |
|---|---|
| * (Frost Protection) | 7°C |
| 1 | 12°C |
| 2 | 16°C |
| 3 | 20°C |
| 4 | 24°C |
| 5 | 28°C |
| MAX | 30°C |
Figure 7.1: Thermostat settings and their approximate temperature values.
The '*' setting activates frost protection, preventing the room temperature from dropping below 7°C, which helps protect pipes from freezing.
8. Maintenance
The EMKE Multiblock Radiator Valve is designed for durability and requires minimal maintenance.
- Cleaning: Wipe the chrome surface with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Regular Checks: Periodically inspect the valve and connections for any signs of wear, corrosion, or leaks.
- Thermostat Exercise: If the heating system is off for extended periods, occasionally rotate the thermostatic head through its full range of settings to prevent internal components from sticking.
9. Troubleshooting
If you encounter issues with your EMKE Multiblock Radiator Valve, refer to the following common problems and solutions:
9.1 Leaks
If a leak occurs, check the following:
- Loose Connections: Ensure all valve connections are properly tightened.
- Missing or Damaged O-rings/Seals: Verify that all necessary O-rings and seals are in place and undamaged. Replace if worn.
- Improper Use of PTFE Tape: Ensure PTFE tape (if used) was applied correctly and sufficiently to threaded connections.
9.2 Radiator Not Heating or Overheating
- Thermostat Setting: Check if the thermostatic head is set to the desired temperature.
- Air in Radiator: Bleed the radiator to release any trapped air.
- Valve Pin Stuck: If the radiator remains cold even with the thermostat set high, the valve pin might be stuck. Carefully remove the thermostatic head and gently press the pin to ensure it moves freely.
If problems persist after attempting these troubleshooting steps, please contact customer support.
