Pneumatic three-way ( Sectional) Pneumatic valve butterfly images

Pneumatic sectional butterfly valve is a kind of pneumatic valve can control the butterfly in 0 & deg; To 90 & deg; Between two times of opening and closing of pneumatic valves, pneumatic actuator mainly consists of a three-stage, two or three of solenoid pneumatic valve and related accessories, through the different ways of power supply of electromagnetic pneumatic valve, pneumatic valve fully open, half open and close, and other functions, to achieve control of the pipe flow.








pneumatic sectional butterfly valve control loop through a set of solenoid pneumatic valve, realize to control the position of the pneumatic valve control, generally have 0 & deg; - 45° - 90° Or 0 & deg; - 90° - 180° Mode of operation, can also be customized according to user's requirements in the middle value, such as 30 & deg; 50度; ,60度; Middle position etc, it also can set 0 - on the spot 60° Set to meet the scene between the different flow of control.







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.
