Lockup device, manual operation, in order to prevent misoperation, valve can be equipped with padlock device.
Anti-static structure, when a fire break out, the metal seal forms to prevent large leakage of media.
Valve body and stem can finish emergency injection seal, through the grease injection valve, the stop-leak compound can achieve a short-time
seal, therefore buying time handling the scene.

It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The upper mounted ultra-low temperature floating ball valve is a valve suitable for ultra-low temperature environments, mainly used to connect or cut off low-temperature media.
