SHUANGLIN VALVE Magnetic Lockable Gate Valve with Check Valve

Smart Access Solution for Modern Utility Networks

As water utilities continue to improve system security and operational efficiency, specialized service valves have become increasingly important. The SHUANGLIN VALVE Magnetic Lockable Gate Valve with Check Valve is engineered to meet these demands by combining magnetic access control, reliable shut-off capability, and integrated backflow protection in a single compact valve.

Designed in DN15–DN25 sizes, the valve can only be operated using a dedicated magnetic key, providing a higher level of security than conventional mechanical locking systems. This specialized operation helps prevent unauthorized access while allowing utility personnel to perform maintenance quickly and efficiently.

The built-in check valve automatically blocks reverse water flow, protecting pipelines, meters, and connected equipment from unwanted pressure changes or contamination. Integrating these functions into one valve simplifies installation and reduces the number of components required within the piping system.

Manufactured from premium forged brass, the valve delivers outstanding durability under continuous service conditions. Precision machining ensures smooth internal operation, dependable sealing, and consistent performance even after years of frequent use.

Its compact structure is particularly suitable for municipal water projects, smart metering systems, public infrastructure, and modern water management applications where secure operation and reliable performance are equally important.
