Ball Valves
Mini and standard BSP lever ball valves for isolating compressed-air pipework, receiver outlets, workshop air lines and individual sections of an installation.
Ball Valves for Compressed-Air Pipework
The range includes compact black mini ball valves in 1/4" and 3/8" BSP, plus standard red-lever female x female valves from 1/4" through to 2" BSP.
A quarter-turn ball valve gives a simple and practical way to isolate equipment or sections of pipework for routine operation, servicing, extensions and maintenance.
Choose the valve by BSP size, connection type and system requirements. Mini valves are particularly useful where installation space is limited.

Typical Ball Valve Applications
Air Receiver Outlets
Provide a straightforward isolation point between the receiver and downstream pipework.
Machine Drops
Allow individual machines or workstations to be isolated without shutting down the entire air system.
Pipework Sections
Section valves can make extensions, maintenance and fault finding more practical.
Filters & Air Treatment
Suitable isolation points can help make downstream equipment easier to service when correctly installed.
How to Choose the Correct Ball Valve
BSP Size
Match the valve to the thread size of the pipework, receiver or component connection.
Connection Type
Check whether the installation requires female x female or male x female threads.
Available Space
Mini ball valves are useful where there is limited clearance around the connection or operating handle.
System Duty
Confirm the selected valve is suitable for the pressure, medium and installation requirements before use.
Ball Valve Installation Guidance
- Fully isolate and depressurise the compressed-air system before installation
- Use the correct mating BSP threads and suitable sealing method
- Avoid excessive tightening or applying unnecessary load to the valve body
- Position the handle where it can be operated safely and easily
- Support adjacent pipework so the valve is not carrying unnecessary mechanical load
- Check all joints for leakage after the system has been safely repressurised

Ball Valve FAQs
What sizes of ball valve are available?
The current range includes mini 1/4" and 3/8" BSP valves, plus standard female x female valves from 1/4" to 2" BSP.
What is the difference between a mini and standard ball valve?
A mini valve has a more compact body and handle arrangement, making it useful where installation space is limited. The standard range is available in a wider spread of BSP sizes.
What does female x female mean?
Both threaded valve connections are female. A male x female valve has one male threaded end and one female threaded end.
Can a ball valve be used to isolate part of a compressed-air system?
Yes. Ball valves are commonly used as isolation points for sections of pipework, receivers and equipment when correctly specified and installed.
Should I use a ball valve to regulate airflow?
Ball valves are primarily used for on/off isolation. Where controlled downstream pressure is required, use a suitable air pressure regulator.
Can Compressed Air Systems UK help with pipework fittings?
Yes. We supply valves, fittings, brackets and related compressed-air pipework components and can also assist with installation projects.
