Key Points of Use and Installation

1. The working pressure of the pneumatic head is 0.4-0.8 Mpa, and the working medium is clean dry air.

2.3 "and 4" butterfly valves are operated with 80x90, and the square outlet of the output shaft is 12x12mm.

5 "and 6" butterfly valve adopts 125x90 degree head, and the square outlet of output shaft is 16x16mm.

8 "and 10" butterfly valve adopts 160x90 degree head, and the square outlet of the output shaft is 22x22mm.

3. The pneumatic head is equipped with A intake and B intake. When A intake (G1/4") is intake, the butterfly valve opens; B intake (G1/4"); and the intake butterfly valve closes. The intake hose is 10x1mm.

4. The indicated position of the butterfly valve position display must be in accordance with the actual position (on or off) of the butterfly valve.

5. The reserved space for installing butterfly valves is the same as the thickness of butterfly valves. The thickness data of butterfly valves are shown in the attached figure.

6. No additional soft gaskets shall be added between the joint surface of the valve and flange to remove impurities at the pipe orifice so as not to obstruct the Inter-valve switch.

7. The flange surfaces of the pipelines on both sides of the valve must be parallel and coaxial. No bigger inclination is allowed to ensure the clamping and normal operation of the valve.

8. In the installation position of butterfly valve, attention should be paid to the tightening sequence of flange connecting bolts, and the force should be uniform.
