Pneumatic flange gate valve,flange gate valve,Pneumatic gate valve,gate valve,

Structural characteristics

1, the valve stem and surface by nitriding treatment, has good corrosion resistance, abrasion resistance and wear resistance.

2, can use a variety of pipe flange and flange sealing surface form, to meet various working conditions and user requirements.

3, Using wedge type elastic ram structure, large diameter thrust bearing, small friction, and equipped with impact manual, easy to open and close.

4, gate, seat wear resistance, high temperature resistance, corrosion resistance, good abrasion resistance, long service life.

5, the body material variety is complete, fillers, gaskets can be reasonably selected according to the actual working conditions or user requirements, can be applied to a variety of pressure, temperature and medium conditions.

The pneumatic flanged gate valve is mainly composed of flanged cast steel gate valve and pneumatic actuator. It is a kind of automatic control valve driven by compressed air of the actuator. It has two modes of action: gas opening and gas closing. It can be equipped with an electrical or gas return device to send the status information of the valve switch, which can achieve remote control, centralized control and automatic control. The double-layer cylinder structure and buffer mechanism is used, which doubles the lifting force compared with the single-cylinder pneumatic gate valve, can effectively slow down 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 can also avoid the phenomenon of the gate stuck.

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.
