Flange Connection Ball Valve

The fluid resistance of the ball valve is the smallest of all valves, even for shrink ball valves. PRODUCT DESCRIPTION   Product Characteristics   A. Small fluid resistance   Low fluid resistance. The fluid resistance of the ball valve is the smallest of all valves, even for shrink ball valves.   B. Good sealing   Good sealed seat. The sealing ring made of elastic materials such as PTFE is easy to seal, and the sealing capacity of the ball valve increases with the medium pressure.   C. Good self-lubrication   Because the PTFE has good self-lubrication characteristics, the friction loss with the ball valve is small, and the service life of the ball valve is long.       Advantages of a Flange Ball Valve   A. High-level platform design that meets the ISO5211 standards   The drive installation platform, designed according to ISO5211 standards, can directly install all kinds of drives, and have two sets of PCD for customers to choose from   B. Subinking cover design   This cover is designed to prevent leakage of the valve stem and the valve body without removing the drive device for on-site use.   C. Design of double-layer butterfly-shaped shrapnel device   Two butterfly-shaped shrapnel prepressed in advance will compensate for the microleakage of the valve stem, releasing the deformation of the ride prepressed and pressing the fill again.   D. Third heavy seal design of valve stem "O" type ring   When the stem turns, the "O" ring can reduce the direct friction of the stem to the valve body, and can assist the stem part at the low pressure. If the pipe medium is gas, the "O" ring is better sealed than the PTEE.   E. explosion-proof design of valve stem   The structural design of the stem and body can prevent the stem from rushing from the body due to excessive pressure in the chamber.   F. Design of the sealing lines   A concentric positioning seal structure between the valve body and the valve cover can prevent leakage of excess material and movement when the sealing line extrusion.   G. Anti-static electricity design   Through the static contact of the spring behind the ball, the ball body friction to the valve stem.   I. fire protection planning   When a fire occurs on site, the valve seat is burned or vaporized under the influence of high temperature.
