V&G Compression 15mm Lockshield Gate Valve

The V&G Compression 15mm Lockshield Gate Valve is a reliable and tamper-resistant solution for controlling water flow within domestic or commercial plumbing systems. Crafted from durable brass, this valve is designed to connect two lengths of 15mm copper pipe and is suitable for both hot and cold water applications. This lockshield gate valve uses compression fittings, which means installation is straightforward and clean—no soldering, heat, or flux required. Simply insert the copper pipes into each end and tighten the nuts using standard spanners to create a secure, watertight seal. What makes this valve especially useful is its lockshield design. Unlike standard gate valves that feature an exposed handle, the lockshield model can only be adjusted with a special tool. This makes it ideal for situations where the water flow should be set and left undisturbed—such as in balancing heating systems or preventing unauthorised tampering in shared or commercial properties. This product is WRAS approved (Approval Number: 1304903), meaning it meets high standards for safety and quality in potable water systems.
