Pneumatic O-type Cut-Off Ball Valve

Overview Of Pneumatic O-Type Cut-Off Ball Valve
 O-type pneumatic cut-off ball valve pneumatic actuator using the new AT/GT series of pneumatic actuators, the structure of national utility model patents, there are double and single acting type (spring), with rack and pinion drive structure, the performance is more safe and reliable.
 
 First, Brief Introduction Of Pneumatic O-type Cut-Off Ball Valve
 O-type pneumatic cut-off ball valve pneumatic actuator using the new AT/GT series of pneumatic actuators, the structure of national utility model patents, there are double and single acting type (spring), with rack and pinion drive structure, the performance is more safe and reliable; large diameter valves pneumatic actuator using AW, dial fork type transmission structure, reasonable structure, large output torque.
 
 Pneumatic O-type cut-off ball valve has one second time to cut off the closed ball valve, equipped with explosion-proof device, which can be cut off by gas. Is the ball valve and single acting piston pneumatic actuator which is widely used in natural gas, oil, chemical industry, metallurgy, papermaking, power plants, mining, printing and dyeing, pharmaceutical, chemical, food and beverage, water treatment and air treatment industry cut off control, and automated gas dynamic instrument.
 
 Two, Pneumatic O-type Cut-Off Valve Working Principle
 Pneumatic O-type cut-off ball valve consists of valve body, ball, valve shaft, sealing ring, packing, pressure plate and other components. The actuating mechanism consists of gas, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bush, adjusting bolt, "O" ring, and other main components. The actuator and valve is connected with the connecting shaft, cylinder pressure input, acting on the piston to produce certain thrust, the gear type output in piston driven gear output shaft to rotate the valve, drive shaft rotation, so that the ball valve in the valve with the rotation, change the valve flow area to change through medium flow valve to.
 
 Three, Pneumatic O-type Cut-Off Ball Valve Product Characteristics
 1, Thrust bearing reduces the friction torque of the stem, so that the valve stem can be operated stably and flexibly for a long time.
 2, The valve seat sealing performance is good, using PTFE and other elastic materials made of sealing ring.
 3, Anti-static function: in the sphere, stem, valve set between the spring, can switch the process of static electricity export.
 4, The stem seal is reliable, because the valve stem only for rotational movement and without lifting movement, stem packing seal is not easy to destroy.
 5, Because PTFE and other materials have good self lubrication, and ball friction loss is small, so the ball valve has a long service life.
 6, Cutting speed is fast, with one second time cutting ability, and sealing performance is good, can be equipped with explosion-proof device, can be cut off by gas pipeline.
