Improvement of valve seat sealing structure of pneumatic ball valve Soft seal pneumatic ball valve is usually the first choice in the selection of pneumatic ball valve because of its simple manufacturing, reliable sealing and low cost.

Precautions for installation of stainless steel flexible joint:
1. The other end of the stainless steel flexible joint on the pipeline away from the vibration source shall be effectively fixed so that the flexible joint can isolate and absorb vibration.
2. When the electric welding operation is stopped at the construction site, the bellows shall be effectively protected to prevent the welding slag from splashing the bellows.
3. Stainless steel flexible joints must be installed in a straight line without bending or translation.
4. After installation, the nuts and spare nuts on the pull rod shall be locked, and the pull rod and nuts shall not be removed.
5. The medium shall not be corrosive to the corrugated pipe material, and the chloride ion content in the medium shall be ≤ 25PPM.
6. During the installation of stainless steel flexible joints, the product length can be properly adjusted by using the pull rod, and the adjustment amount shall not be greater than the regular value.
How to Use Stainless Steel Pneumatic Butterfly Valve Correctly
First, the design temperature of stainless steel hose is - 20 ℃~+400 ℃, so this temperature can be met.
Secondly, the diameter of your hose selection does not depend on the pressure, but on the diameter of the pipe connected with the stainless steel hose according to the drawing. The smaller the diameter of the ordinary pipe, the stronger the pressure it bears.
