Pneumatic flange ball valves
ZSHR Pneumatic "O"-shaped cut off ball valve is composed by the pneumatic double acting or single acting actuators and ball valve. it has a simple structure, reliable sealing, small size, light weight, etc. features. It can be widely used in petrochemical, chemical, light industry, making paper and other industrial process control systems.
The actuator is the imported dual-piston and gear-rack pneumatic actuator, with features of light weight, small size, large output force, a long service life and so on. The actuator consists of the cylinder, cylinder gland, piston (rack), "O"-ring, piston bearings, guide ring, gear (output shaft), bearing, adjusting bolt and other parts.
The ball valve is floating structure that under the digestion and absorption of foreign advanced technology. It uses the flexible seat with flexibility, even after the seat worn, it can also maintain the reliable sealing because of its compensation remain sealed and reliable, the small operating torque, and a long service life. With the stem of inverted sealing structure, the sealing is reliable, allows to replace the packing on site under normal pressure.
When the air supply signal input the air chamber of pneumatic actuator, the pressure acting on the piston, and producing thrust, rack drive gear shaft rotation, making the stem and ball rotating, in order to achieve the open and close action of the ball valve.
