STAINLESS STEEL CRYOGENIC BALL VALVE

Product Description

The top entry ball valve is mainly used on pipelines and industrial systems. It has such advantages as top online maintenance function, small fluid resistance, simple structure, reliable sealing, convenient operation and maintenance, rapid on-off operation, flexible opening and closing, etc. Cryogenic top entry floating ball valve is suitable for medium temperature -40℃ ~ -196℃,cryogenic ball valve is called low temperature ball valve,Cryogenic top entry floating ball valve is mainly used for ethylene, liquefied natural gas (LNG) plant, gas LPG, LNG storage tanks to accept base and goonhilly, air separation equipment, oil chemical tail gas separation equipment, liquid oxygen, liquid nitrogen, liquid argon, carbon dioxide cryogenic storage tank and tank lorry, psa oxygen generating device, etc.

Integral structure

The body adopts the integral structure, so as to ensure that it has enough strength and rigidity under the maximum rated working pressure. The valve trims have been carefully designed and selected to ensure reliability under various service conditions. The sufficient wall thickness and the connection bolts of high strength are very helpful to the maintenance and servicing of valves and are able to endure pipelines stress.

Structure

The vale adopts the top entry structure. The most distinctive difference between this kind of valve and others is that the online maintenance function can be realized without the need of removing the valve from the pipeline. The seat adopts the concession type seat structure, and the rear end of the seat retainer is set as oblique angle to prevent impurities accumulated on the seat from influencing the concession of seat.
