Pneumatic center line butterfly valve Overview:

Pneumatic butterfly valve refers to the rotary center of the butterfly valve plate (that is, the center of the valve shaft) and the center of the valve body to form a straight line, using a direct connection method to connect with the pneumatic actuator, according to the different connection methods can be divided into pneumatic clamp butterfly valve and pneumatic flange butterfly valve, the disc has an automatic center function (up and down, left and right), its sealing form is generally made of sealing structure, Common sealing materials are rubber, polytetrafluoroethylene and so on. The disadvantage is that because the opening and closing of the butterfly plate and the valve seat are always in a state of extrusion, it is easy to scratch, resulting in fast wear.

Pneumatic center line butterfly valve performance characteristics:

The contact surface of the upper and lower ends of the butterfly plate is relatively wide, the friction is large when switching, and the torque switch is relatively large. Regardless of whether the valve is open or closed, the lower end of the sealing surface of the butterfly plate and the valve core and the valve seat are in a sealed compression state, with excellent sealing performance.

Pneumatic center line butterfly valve application:

Because of the simple structure, no directional sealing restrictions, the center symmetry (type I) two-way sealing effect is the same, and the flow resistance is small, the switching torque is also small, the pressure capacity is positioned as low and medium pressure, so it is widely used in the working conditions below 1.6MPa. There is generally no direction requirement when installing, it can be repaired and disassembled on site, and the sealing ring can be replaced without completely disassembling the valve.

Application: gas, water, oil, corrosive media, etc

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.
