Pneumatic segment control ball valve

Pneumatic segment control ball valve introduction:
Pneumatic segment control ball valve is V notch ball design for good regulating performance,Pneumatic segment control ball valve used at temperature (soft seat:-40~200℃) and high temperature (metal seat:-60~450℃).Pneumatic segment control ball valve features high transmission efficiency, large thrust, good sealing performance, large rated flow coefficient and strong interchangeability of parts.Pneumatic segment control ball valve trim and the seat is closed when the "shear" action, Pneumatic segment control ball valve can be especially used in the medium containing fiber filaments, particles or very high viscosity conditions.Pneumatic segment control ball valve is widely used in papermaking, petroleum, chemical, pharmaceutical, metallurgy, light textile, sewage treatment and other production departments of gas, steam, liquid transport pipeline medium flow rate, pressure, liquid level, temperature regulation, in order to achieve automatic control process production process according to certain specifications.
