Pneumatic low temperature butterfly valve:low temperature butterfly valve: butterfly valve

Pneumatic low temperature butterfly valve Overview:

Pneumatic low temperature butterfly valve is mainly suitable for the medium temperature of -40℃ ~ -196℃ liquid nitrogen (cryogenic) medium in low temperature conditions, in order to ensure that the low temperature butterfly valve can operate safely and reliably at low temperatures, valve parts have been cryogenic treatment before finishing, the valve cover is a long neck structure, its purpose is to protect the function of the stuffing box, so that the stuffing box is far from the low temperature position. Ensure the sealing effect of the packing. The medium used in pneumatic butterfly valve is usually liquid helium, liquid hydrogen, liquefied natural gas, liquid nitrogen, liquid oxygen and other low temperature fluids.

Pneumatic low temperature butterfly valve features:

The material of the pressure part of the pneumatic butterfly valve can withstand the expansion and contraction caused by the change of the temperature of the medium, and the structure of the sealing part will not produce the best deformation when the temperature changes. The extended upper valve cover adopts the double sealing of the valve shaft to ensure the long-term stability of the sealing packing at low temperatures, so it is widely used in the control of cryogenic fluid processes such as liquefied natural gas and air separation industries.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
