Product Information
Full details
The 22mm Lockshield Gate Valve is an essential component for professional plumbers and DIY enthusiasts who need to isolate specific sections of a water supply system for maintenance or repairs. Its primary benefit is the ability to shut off water locally, preventing the need to drain the entire building's plumbing; however, users should note that the lockshield design requires a specific key for operation, which prevents unauthorized adjustments but can be inconvenient if the key is misplaced.

FAQs
Can I use this on a heating system?
Yes, this valve is suitable for standard domestic water and central heating pipework.
What is the benefit of a lockshield over a standard gate valve?
A lockshield valve prevents unauthorized users from turning the water on or off, as it requires a specific key.
Do I need any special tools to install this?
No, you only need two appropriately sized wrenches to tighten the compression nuts.
Is the valve supplied with a key?
Please check your package contents, as the key is typically required to operate this specific valve design.
Can this valve be installed vertically?
Yes, this gate valve can be installed in both horizontal and vertical pipe orientations.
Troubleshooting
Leakage at the compression joint
Ensure the pipe is cut square and is free of debris. Tighten the compression nut further, or if the olive is damaged, replace the olive.
Valve will not turn
Check that you are using the correct lockshield key. If the valve is seized, gently apply penetrating oil and attempt to rock the spindle back and forth to loosen it.
Pros and Cons
Pros
- Eliminates the need to drain the entire system for local repairs
- Secure compression fittings ensure a watertight seal
- Tamper-proof design keeps valves in the desired position
- Easy to install with basic plumbing tools
Cons
- Requires a specific key for operation
- Not suitable for fine-tuning flow rates as it is designed for full open/close positions
- Requires periodic checks to ensure the valve stem remains loose
Setup, Compatibility & Care
To install, ensure the pipe ends are clean and free of burrs. Slide the nut and olive onto the pipe before inserting the pipe into the valve body. Tighten the nut by hand, then use a wrench to complete the seal with an extra half-turn. Do not overtighten, as this can deform the olive. For long-term care, occasionally turn the valve spindle to prevent mineral build-up or 'seizing,' which can occur in hard water areas. Always keep the lockshield key in a secure, accessible location.
