Welding Side Mounted Ultra-low Temperature Butterfly Valve

overview

LNG (liquefied natural gas) is a clean and efficient energy source. Ultra low temperature butterfly valve is a key regulating valve in natural gas liquefaction and storage equipment, widely used in LNG receiving stations, natural gas liquefaction units, LNG refueling stations and other LNG storage and transportation systems. Side mounted ultra-low temperature butterfly valve is a specialized ultra-low temperature butterfly valve designed specifically for LNG working conditions and capable of online maintenance.

Structural characteristics

Triple eccentric structure: torque seal, butterfly plate opening and closing action without interference throughout the entire process.

Valve inspection and repair door structure: realize online maintenance and repair of valves, and replace key components.

Long neck valve cover and drip board: prevent the packing from freezing at low temperatures, eliminate condensation or rainwater from flowing into the insulation layer.

Detachable valve seat and floating sealing ring: conducive to the maintenance and replacement of sealing pairs, solving the problem of bi-directional sealing for ultra-low temperature butterfly valves.

Low leakage combination packing: Achieve zero leakage sealing of packing for ultra-low temperature operation, meeting the low leakage requirements of LNG pipelines.
