The gas gate valve is a device used to open and close the pipeline passage or regulate the flow of the medium in the pipeline. It is the main cut-off and regulating device on the gas pipeline. Therefore, it is required to be safe, reliable and durable. When it needs to be shut down during production operations, it should ensure a tight seal without gas leakage. During maintenance, the gas source should be cut off without the possibility of leakage into the gas cut-off side. Moreover, it should be considered for wear resistance and corrosion resistance to ensure a long service life.

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.
