High performance low temperature side mounted butterfly valve，Low temperature butterfly valve，Butterfly valve

Main features:

1 According to the requirements of working conditions, the low-temperature butterfly valve has a top structure and a side-mounted structure, with flanges, clamping, butt welding and lugs and other connection methods.

2 Based on the inflammable and explosive characteristics of low-temperature media such as LPG and LNG, the low-temperature butterfly valve is designed with fire-proof and anti-static measures.

3 For the temperature above -50℃, generally do not use a long neck structure, for the temperature below -50℃ ball valve, the neck is a long neck structure.

4 Low temperature ball valve is suitable for the management system of low temperature liquid storage and transportation equipment, has the characteristics of flexible switching and reliable sealing, and can also be used for other low temperature and cryogenic media management systems.

5 The driving mode of the low-temperature ball valve is manual, worm gear transmission, pneumatic or electric.

6 Top type low temperature butterfly valve can be repaired online, easy maintenance.

Low temperature butterfly valve refers to the butterfly valve that can be used in low temperature conditions, usually the butterfly valve with a working temperature below -40 ° C is called low temperature butterfly valve, mainly used in ethylene, liquefied natural gas and other chemical equipment. The output liquid low-temperature media such as ethylene, liquid oxygen, liquid hydrogen, liquefied natural gas, liquefied petroleum products, etc., are not only flammable and explosive, but also gasification when heating up, and the volume expands hundreds of times when gasification. Low temperature butterfly valve is one of the indispensable important equipment in petrochemical, air separation, natural gas and other industries, and its quality determines whether it can be safely, economically and sustainably produced.

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.
