Characteristics of Pneumatic Operated Butterfly Valves
- Actuator: It is made of hard anodized aluminum which is an anti-corrosion material.
- Pinion: It is constructed using nickel plated steel that helps in reducing friction to a great extent.
- Piston: It is made of POM material which is highly durable than aluminum.
- Butterfly valve body: It is made of ductile iron coated with epoxy which also an anti-corrosion material.
- Disc: It is manufactured with zinc plated steel or with ductile iron zinc plated stainless steel.
- Shaft: It is of AISI 430 stainless steel material which is not wetted.
Working Principle of Pneumatic Wafer Butterfly Valves
The basic working principle of pneumatic valve is that compressed air enters in the pneumatic actuator to drive the piston, and then its start rotating or lifting torsion shaft which drives the stem. Pneumatic Butterfly Valve is a circular disc rotating with the stem as an opening and closing function, in order to achieve the opening action of the pneumatic valve, mainly for the use of cut-off Valve, it can also be designed to have the function of regulation or section valve and regulation At present, the use of pneumatic butterfly valve in low pressure large and medium diameter pipeline is more and more.
