Pneumatic type O characteristics and structure principle of pneumatic control valve

Pneumatic type O cut the ball valve and pneumatic actuators with double acting. It has simple structure, small volume, light weight, convenient operation, can be widely used in petroleum, chemical industry, hydropower, textile and other industrial production process automatic adjustment and remote control. O-type ball valve consists of body, ball, valve shaft, seal ring, filler, pressure plate and other components. Type actuator by gas, piston, gear, output shaft, cylinder head, bearing, guide ring and piston bush, adjusting bolt, o-rings and other major parts. Its principle is connected to the valve with actuator shaft connection. After the input air pressure in the cylinder, produce certain thrust acting on the piston, gear type and output in the piston, driven by gear output shaft to rotate, drives the valve spindle rotation, so that the ball valve ball inside the valve with rotation, change valve flow area, achieve change through valve within the medium flow.
