Structural characteristics
1, the bottom of the valve is provided with a sewage box, easy to clean dirt and impurities, and can be smoothly through the pipeline cleaner.
2, the valve stem adopts large guide program thread drive, which can realize fast opening and closing.
3, the use of friction power is minimal, can automatically lubricated, and resistant to gas and various corrosive gases of high-performance packing, flexible operation, reliable sealing.
4, excellent sealing performance, the operation can automatically remove the sealing surface dirt, maintain a tight seal.
5, low fluid resistance. The medium channel inside the gate valve body is straight through, and the flow direction is not changed when the medium flows through the gate valve, so the flow resistance is small.
6, less effort to open and close. When opening and closing, the motion direction of the ram is perpendicular to the flow direction of the medium. Compared with the globe valve, the gate valve is easier to open and close.
7, the flow direction of the medium is generally not limited. The medium can flow from both sides of the gate valve in any direction, and can achieve the purpose of connecting or cutting. Easy to install, suitable for use in pipelines where the flow direction of the medium may change.
Manual gas gate valve is mainly used in coal gas, metallurgy, coking and other industries of gas production and city gas transmission and distribution network. Applicable media are: blast furnace gas, coke oven gas, producer gas, water gas, oil gas and other dirty gas and liquefied gas, natural gas, mine gas and other clean gas.
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.
