Pneumatic three-way ( The three type) Pneumatic ball valve

Pneumatic three-way ball valve, also known as the three type pneumatic ball valve, it can provide pneumatic ball valve in the 0 & deg; To 90 & deg; Between 0 & deg; ,45° ,90° Or 0 & deg; ,60° 90度; Three type of operation mode, through the two auxiliary mechanical brake piston movement, to achieve the intermediate position of the adjustable, achieve control of the pipe flow, generally use occasion is in the oil and chemical products in bulk in the system.








pneumatic three-way ball valve usually consists of a three-stage pneumatic actuators, two or three of solenoid pneumatic valve and related accessories, through the change of additional cylinder piston stroke, actuators, and pneumatic valve Angle is stopped in the preset Angle ( 45° - 90° ) Pneumatic valve flow, so to adjust, the device by two solenoid pneumatic valve pneumatic control valve flow. This device after the adjustment to the need to position, can keep in long the cycle time of constant measuring accuracy.








the three type pneumatic sectional pneumatic ball valve can realize the pneumatic ball valve in the 0 & deg; To 90 & deg; Between two times of opening and closing, the control pipe flow, makes much of its application in oil and chemical products in bulk system, configuration of explosion-proof limit switch, explosion-proof solenoid pneumatic valve and other accessories, can be used in harsh industrial needs.






position 1 ( The middle)


air pressure into the mouth and 2 D mouth at the same time, to expel air from four and C, 2 as internal piston moving mouth, mouth D by auxiliary piston push rod limit internal piston position at a predetermined location in the middle.






position 2 ( Full open position)


air pressure into the 2 port and C port at the same time, to expel air from four and D, 2 internal piston moving mouth, C taste its auxiliary piston push rod position, make the internal piston smoothly to achieve full open position.





position 3 ( Seated position)


air pressure into four, from 2 to expel air, internal piston moving in the direction of middle reaches the seated position. Can provide 0 45 - 90 spring return type specification, the expired without electricity or gas source faults, by spring force inside the piston return to the seated position.
