Stainless Steel Pneumatic Actuated Butterfly Valve manufacturer in India

A351 CF8 304 Hygienic Pneumatic/ Spherical Disc Butterfly Valve manufacturer in India

Pneumatic Butterfly Valves is used to control air or gas in a pipeline. There are different parts such as actuator, pinion, piston, butterfly valve body, disc and shaft. The Pneumatic Operated Butterfly Valve actuator is made up of anodized aluminum. This type of actuator is used to minimize the corrosion. The pinion is made up of nickel plated steel. The piston is made up of highly durable material than aluminum. The Pneumatic Wafer Butterfly Valves are made up of ductile iron body. There are different classifications for different dimensions and pressure capacities. The operation can be of hand lever, worm gear box, pneumatic actuated or electrical actuated. The size range of the valves is between 1 ½ inches to 48 inches.

The Pneumatic Butterfly Valve Dn25 is a lower pressure class. The pressure ranges from ANSI 150 to ANSI 300 or higher. The operating temperature ranges from -25 degrees to 600 degrees Celsius. The pressure capacities range from PN10 to PN16. The Double Acting Pneumatic Butterfly Valve gate resides inside the seating and is not raised outside the shaft during operation. The valve can be coated with PTFE and other types of coatings. The material of the valve body can range from austenitic stainless steel to alloy steel materials as well.

 

• 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.

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.

• Lower investment cost than an electric version.
• Fast opening/closing
• Single acting conserves compressed air and the valve will return to initial position in case of air or power loss.
• Can be equipped with a limit switch box.

• Single acting gives less control than double acting actuators.
• It requires a compressed air system and a solenoid valve to control the air supply.
