SPO Pneumatic Through-Way Ball Valve
SPO Pneumatic through way ball valve is composed of GTX-B series pneumatic rack and pinion
actuators and ball valve body assembly.The ball valves are offered in two basic structures,floating
ball(below DN200) and trunnion mounted ball(above DN250).Special elastic lip seal structure not
only ensure sealing is reliable, but also has good self-cleaning effect for viscosity medium when it
coordinates with cylindrical flow path, especially has shearing and block-risistant functions to the
fluids with fiber.
Full-port design , small fluid pressure loss and different metal and nonmetal combinations can
guarantee reliably conveying and cutting while it being used under -29Ž`450Ž working
temperature.
SPO Pneumatic through-way ball valve is characterized by compact structure, effective handle ,
smooth operation and long lifetime. It can be widely used in petroleum, chemical, metallurgy,
electric power, paper and sewage treatment etc industrial areas.
