Product Name: D671X/D671F Pneumatic Clamp Butterfly ValvePneumatic soft seal butterfly valve

Product Introduction

D671XPneumatic soft seal butterfly valveIt has the characteristics of small size, lightweight and pleasant, reliable performance, simple matching, and high flow capacity, especially suitable for occasions where the medium is viscous, contains particles, or fibers. Pneumatic butterfly valves are widely used in industrial automatic control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemical engineering, teaching and research equipment, and power.

Product Features:

1. The pneumatic butterfly valve body only requires a small installation space, and the task principle is easy and reliable.

2. Pneumatic butterfly valves have great flow performance and minimal pressure loss through the valve.

3. Pneumatic butterfly valves have significant economic benefits, especially for larger diameter butterfly valves.

4. The valve body of the pneumatic butterfly valve is matched with the standard convex pipe flange.

5. Pneumatic butterfly valves have approximately equal percentage flow characteristics and can be used for regulating or on-off control.

6. The special seat seal of pneumatic butterfly valves is suitable for liquids and gases with relatively clean media.

Pneumatic actuator:

The pneumatic butterfly valve adopts a new GTD series or ATD series pneumatic actuator, which has double acting and single acting (spring reset), gear transmission, and is safe and reliable.

1. Gear type dual piston, with large output torque and small volume.

2. The cylinder is made of aluminum material, which is lightweight and aesthetically pleasing.

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

4. The rack and pinion connection can adjust the opening angle and rated flow rate.

5. The actuator can be equipped with live signal feedback indicators and various accessories to achieve automated operation.

6. The IS05211 standard connection provides convenience for the installation and replacement of products.

7. The adjustable screws at both ends can provide a ± 4 ° adjustable range for standard products at 0 ° and 90 °, ensuring synchronization accuracy with the valve.
