The improvement of metal hard seal pneumatic ball valve Under the working conditions of high temperature, high pressure, high flow rate, severe erosion and corrosion, and high strength granular media, hard seal pneumatic ball valve is often used, but this kind of valve has low service life, large leakage, and short warranty period. Our company has studied a kind of erosion resistant ultra hard sealing pneumatic ball valve, and proposed a series of hard sealing pneumatic ball valves with a new concept of high quality, high grade travel, erosion resistance and long warranty period.

Definition of valve: "valve" is a device used to control the direction, pressure and flow of fluid in the fluid system. The valve is a device that can make the medium (liquid, gas, powder) in the piping and equipment flow or stop and control its flow.
