Choosing ball valves
Ball valves are shut-off valves commonly used in central heating systems, water-based heating systems, pipework and technical installations. With simple quarter-turn operation, a pipe section, appliance or component can be quickly isolated for maintenance, service or replacement.
When selecting a valve, connection size, female or male thread, material, pressure rating, temperature rating and bore are important. For additional solutions, also view shut-off valves and control valves for heating systems, check valves for flow protection and sealants for leak-free installation.
Important for ball valves
- Choose the correct connection size, such as G 1/2", G 3/4" or G 1"
- Check whether female thread, male thread or transition fitting matches the pipework
- Pay attention to material, pressure rating, temperature rating and medium suitability
- Use ball valves for clear shut-off during service and maintenance
- Check installation position, operating space and accessibility
- Use suitable sealing materials for a clean and leak-free connection
Ball valves for shut-off, service and maintenance
A ball valve is often installed at points where an installer must be able to isolate quickly later. This includes connections near boilers, heat pumps, buffer tanks, radiators, manifolds, pumps, dirt separators and other fittings. This means the entire system does not always need to be drained during maintenance.
Brass ball valves are popular because of their robust construction, broad usability and practical operation. The lever position immediately shows whether the valve is open or closed. This makes the ball valve suitable for both new installations and replacement within existing systems.
Always check whether the ball valve matches the application, medium, working pressure and temperature of the installation. For professional installation, suitable sealants, matching fittings and good service accessibility are also important.
Frequently asked questions about ball valves
What is a ball valve used for?
A ball valve is used to quickly shut off a pipe, appliance or system component. In heating systems, ball valves are often used for service, maintenance, replacement and temporarily isolating system sections.
Which size ball valve do I need?
The correct size depends on the pipework and the connection of the component. Common sizes are G 1/2", G 3/4" and G 1". Always check the existing connection before ordering.
What does female thread mean on a ball valve?
Female thread means the thread is located on the inside of the connection. The ball valve is then connected to a component or fitting with matching male thread.
Are ball valves suitable for central heating systems?
Yes, ball valves are widely used in central heating and water-based heating systems. Always check whether material, pressure rating, temperature rating and connection size match the installation.
What should an installer check during installation?
An installer should check connection size, thread direction, sealing, flow direction where relevant, working pressure, temperature, lever accessibility and the position within the installation.
