Description

SPHO Pneumatic high pressure O- type ball valvecomponent by GTX-B series Double piston driven angle rack-and pinion pneumatic actuators and valve body. All adopt fixed ball ***** the medium pressure with special design of different metals and nonmetallic sealing combination, Ensure in - **0 ~ *3 operating temperature range, **0Kg/cm2 than in the medium pressure, reliable performance, cutting conveying. SPHO pneumatic high pressure O- type ball valve has compact structure, smooth operation, long service ***** be widely used in petroleum, chemical, metallurgy, electric power, paper, sewage treatment and industrial control field, in order to control the pressure containing fibers and particles and high-pressure difference fluid.
