Import Air-Powered Ball Valve with Flanged Connection(Imported pneumatic soft-seated flanged ball valve, Imported pneumatic stainless steel flanged ball valve, Imported pneumatic on-off ball valve)

Brand: German WerdWODE

Imported pneumatic ball valve bodies have a passage diameter equal to the connection pipe diameter, allowing the medium to flow through with minimal loss. Pneumatic ball valves can be categorized into soft seat and metal seat valves based on their sealing performance. Soft seat valves are suitable for temperatures ≤180On ° occasions, a metal hard seat valve is suitable for temperatures ≤425A pneumatic ball valve is commonly used in applications with stringent sealing requirements. In addition to controlling gases, liquids, and steam media, it is also suitable for controlling wastewater and media containing fibrous impurities. It is widely used in fields such as petrochemicals, metallurgy, light industry, papermaking, power stations, and refrigeration.

Product Features

1Low fluid resistance; the pneumatic flanged ball valve is the type with the least fluid resistance among all valves, even the reduced bore ball valve has relatively low fluid resistance.

2The pneumatic ball valve body is equipped with thrust bearings to reduce the friction torque of the valve stem, allowing for long-term smooth and flexible operation of the valve stem.

3The pneumatic ball valve seat has excellent sealing performance, utilizing sealing rings made of PTFE and other elastic materials. The structure is easy to seal, and the sealing capability increases with the rise of medium pressure.

4The pneumatic ball valve stem is reliably sealed. Since the stem only rotates and does not move up and down, the stuffing box seal of the stem is less prone to damage, and its sealing capability increases with the rise in medium pressure.

5Due to the excellent self-lubricating properties of materials like PTFE, the friction loss with spheres is minimal, thereby extending the service life of pneumatic ball valves.

6The lower section valve rod and the stepped head prevent the valve rod from extruding. In case of fire, if the rod seal is damaged, the stepped head can still form metal contact with the body, ensuring the rod seal remains intact.

7、 Anti-static Function: Springs are set between the sphere, valve stem, and valve body to conduct away static electricity generated during the switching process.

Pneumatic Actuator

Utilizing state-of-the-artGTDSeries orATDSeries of pneumatic actuators, available in double-acting and single-acting (spring return) types, with gear drive, safe and reliable; large-diameter valves utilizeAWSeries pneumatic actuators with fork transmission, structurally reasonable, high output torque, available in double-acting and single-acting types.

1Gear-type double piston, high output torque, compact in size.

2Cylinders are made of lightweight aluminum alloy material, featuring an attractive appearance.

3Manual operation mechanisms can be installed at the top and bottom.

4Rack and pinion connection for adjustable opening angle and rated flow rate.

5Actuators are available with tele signal feedback indication and various accessories for automated operation.

6、IS05211Standard connections facilitate easy installation and replacement of the product.

7Adjustable screws at both ends allow the standard product to0°And90°With ±4°Adjustable range to ensure synchronization accuracy with the valve.
