Lockshield gate valves provide essential flow isolation with added security, preventing unauthorised tampering in critical plumbing systems. These high-quality brass components deliver complete shut-off capability while ensuring minimal pressure loss when fully open - perfect for installations where maintaining system integrity is paramount.
Understanding Lockshield Gate Valves
Unlike standard handwheel variants, lockshield gate valves feature a protective cap that requires a special key for operation. This additional security measure makes them ideal for installations where access restriction is necessary, preventing accidental or unauthorised adjustment of system flow.
The operation principle remains straightforward - turning the stem raises or lowers an internal gate to control flow. These valves are specifically engineered for full-open or full-closed positions rather than flow regulation, making them distinct from control or regulating valves. Their design ensures minimal flow interruption when open, preserving system pressure integrity.

Professional Applications
Lockshield gate valves serve critical functions across various plumbing installations where security is essential:
- Commercial Buildings - Prevent unauthorised adjustment in public facilities
- Shared Accommodation - Maintain system integrity in multi-occupancy buildings
- Critical Water Systems - Secure isolation points in sensitive applications
- Plant Rooms - Control access to key system components
The full-bore design ensures minimal pressure drop when open, making these valves particularly valuable in systems where maintaining flow characteristics is essential. When installation is complete, the lockshield provides peace of mind that system settings remain uncompromised.
Installation Considerations
When selecting and installing lockshield gate valves, consider these key factors:
- Size Selection - Available in standard 15mm and 22mm compression fittings to match common pipework dimensions
- Accessibility - Position valves where maintenance access is possible while maintaining security benefits
- System Compatibility - Suitable for use with BS EN 1057 pipework across the full temperature range
- Key Management - Establish protocols for securing and accessing valve operation keys
The compression connections ensure compatibility with standard copper pipework, while the brass construction provides excellent durability in various environments. Their non-rising stem design makes these valves suitable for installations where space is limited.
