Magnetic Locking Upstream Gate Valve

SHUANGLIN VALVE Brass Mechanical Lock Telescopic Gate Valve – Upstream Meter Isolation Valve DN15-DN25

The SHUANGLIN VALVE Brass Mechanical Lock Telescopic Gate Valve is a specialized isolation valve designed for installation upstream of water meters in utility and building supply systems. It combines three essential functions in one unit: mechanical key-operated security, telescopic length adjustment for flexible installation, and reliable gate valve shut-off. This integrated design eliminates the need for separate locking devices and pipe alignment fittings, saving installation time and reducing potential leakage points.

The valve’s mechanical locking mechanism requires a dedicated key or tool for operation, effectively preventing unauthorized access, tampering, and theft. This physical lock is particularly valuable for outdoor meter pits, utility rooms, and other exposed installations where security is a concern. The telescopic (expanding) body allows for length adjustment during installation, accommodating variations in pipe spacing and simplifying alignment. This feature is especially useful in retrofit projects and systems where precise pipe positioning is challenging.

Constructed from high-quality forged brass, SHUANGLIN VALVE lockable valves offer excellent corrosion resistance, high strength, and reliable sealing performance. The non-rising stem design enables installation in confined spaces such as meter pits and equipment rooms. The straight-through flow path minimizes pressure drop and ensures maximum flow capacity. Available in DN15, DN20, and DN25 sizes with standard threaded connections, these valves are rated to PN16 (1.6MPa) with a working temperature range of -10°C to 120°C, suitable for water and other non-corrosive fluids. SHUANGLIN VALVE products are manufactured under strict quality control and comply with ISO9001 and CE standards.
