1. This valve utilizes a triple eccentric seal structure, with the valve seat and butterfly plate experiencing minimal wear, featuring a sealing function that tightens with use.

2. Seals are made of stainless steel, offering both the benefits of metallic hard sealing and elastic sealing. They maintain excellent sealing performance in both low and high temperatures, and are characterized by corrosion resistance and long service life.

3. The disk sealing surface is coated with cobalt-based hard alloy, which boasts wear resistance and a long service life.

4. Large-scale butterfly plates are constructed with a latticed frame, offering high strength, a large flow area, and low flow resistance.

5. This valve features bidirectional sealing capability, allowing for installation without restriction based on the medium's flow direction or spatial position, and can be installed in any direction.

6. The drive unit can be installed at multiple positions (rotating 90° or 180°) for user convenience. Actuator

Utilizing the latest series GT pneumatic actuators, featuring double-acting and single-acting (spring return) options, gear-driven for safety and reliability; large bore valves are equipped with series AW pneumatic actuators using fork-type transmission, with a rational structure and high output torque, available in both double-acting and single-acting versions.

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

2. Cylinder made of aluminum alloy, lightweight and aesthetically pleasing.

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

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

5. Actuators are available with optional signal feedback indicators and various accessories for automated operation.

6. ISO 05211 standard connection facilitates the installation and replacement of the product.

7. The adjustable set screws at both ends allow for a ±4° adjustable range at 0° and 90°, ensuring synchronous accuracy with the valve. Optional accessories
