Pneumatic manual wedge gate valves are low-stand open-stem gate valves with pneumatic actuators (double cylinder with buffer mechanism) and manual and protective mechanisms (manual and self-locking pneumato-manual changeover devices). Compared with single-cylinder pneumatic gate valve, the lifting force of the valve is doubled due to the double-layer cylinder structure. This fundamentally solves the problem that some valve bodies of single-cylinder pneumatic gate valves are dead and cannot be opened. Moreover, because the valve has a buffer mechanism, it can effectively slow down and light the wear of the valve plate sealing surface and the valve body sealing surface caused by the downward impact of the piston when the valve is closed, and at the same time, it can avoid the phenomenon of the gate stuck.
Due to its advanced technology, reliable performance, convenient operation and maintenance, it has been widely used as a pipeline opening and closing device for conveying gas and liquid media in petroleum, chemical, metallurgy, electric power, Marine and other departments.

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.
