Product Information
Full details
The Reliance 1/2in Lever Ball Valve is designed for professional plumbers and dedicated DIYers who need a dependable, long-lasting shut-off solution for domestic and commercial water systems. Its primary benefit is the full bore design that prevents flow restriction, ensuring maximum efficiency throughout your plumbing network. While it offers industry-leading durability and high-pressure ratings, users should note that it requires enough physical clearance around the installation point to accommodate the full swing of the lever handle.

FAQs
Is this valve suitable for central heating systems?
Yes, the Reliance Ball Valve is rated for high pressure and is suitable for both hot and cold water plumbing, including standard central heating loops.
Can I use this valve to regulate the flow of water?
No, ball valves are designed for 'on/off' isolation only. Using them in a partially open position to throttle flow can cause premature wear and damage to the internal seals.
What does 'PN40' mean?
PN40 indicates the valve is pressure rated to 40 bar, confirming it is robust enough for most domestic and many light commercial pressure requirements.
Is it compatible with copper pipe?
The valve has female BSP threads. You will need to use male iron or male-threaded copper adapters to connect it to standard copper pipework.
Which way is open?
When the lever is parallel to the pipe, the valve is open. When it is perpendicular (at a 90-degree angle) to the pipe, it is closed.
Troubleshooting
Valve is difficult to turn
Check for debris inside the valve or mineral deposit buildup. Cycling the handle back and forth several times can often clear minor obstructions.
Slight weeping from the thread connection
Ensure sufficient PTFE tape was applied. If it continues, remove the valve, clean the threads, re-apply a fresh layer of tape, and retighten.
Leak from the lever stem
The stem seal is generally non-serviceable; if it leaks, the unit should be replaced to prevent water damage.
Pros and Cons
Pros
- High-pressure PN40 rating for demanding systems
- Full bore internal diameter prevents flow restriction
- Corrosion-resistant nickel-plated finish
- Easy-to-operate lever design
- Standard BSP compatibility for easy fitting
Cons
- Requires more installation clearance than compact service valves
- Lever handle may be obstructed in very tight pipe boxing
- Not intended for throttling or flow regulation
Setup, Compatibility & Care
To install this valve, ensure your pipe ends are cut square and deburred to prevent damage to internal seals. Use appropriate thread seal tape (PTFE) on the male pipe threads before tightening the valve onto the pipework. Always use two wrenches when tightening: one to hold the pipe and one to turn the valve body to avoid twisting the pipework behind the wall.
- Compatibility: Designed specifically for 1/2 inch BSP threaded male pipe connections.
- Care: Periodically cycle the valve (open and close it) every 6-12 months to prevent mineral buildup and ensure the ball mechanism moves freely. Do not use chemical cleaners that may damage the nickel plating.
