Fittings, valves, unions
This category includes a range of heating system components such as thermostatic valves, manual valves and taps, regulating fittings, thermostatic and electrothermal heads, connection kits and OPTIMA bathroom fittings. These products are used to connect radiators, underfloor convectors and bathroom towel rails to single or double pipe systems. The components are designed for precise temperature control, system balancing and safe operation in residential and commercial heating applications.
Products are available in brass construction and include complete sets for heating element connections, as well as dynamic and thermostatic series valves. They are suitable for both new installations and system upgrades, ensuring compatibility with standard heating pipe layouts and control systems.
How to choose
- Match the thread type and size to the pipe or fitting dimensions in the existing system.
- Select the appropriate valve type (thermostatic, manual or dynamic) based on the control method required.
- Ensure material compatibility with the system components, particularly for brass fittings used in wet systems.
- Verify system compatibility with the heating layout (single or double pipe) and control strategy.
- Use complete connection kits for simplified installation and leak-free operation in new setups.
