Product name: D673H pneumatic wafer hard seal butterfly valve

Features of hard seal butterfly valve:

1. The butterfly valve uses stainless steel "U" shaped sealing ring with certain elasticity, and the sealing performance of the butterfly plate is very good regardless of the high temperature.

2. After the 3D eccentricity of the butterfly valve is strictly calculated, the "U" seal ring and the butterfly plate have little friction, long service life and normal function. Tighter and tighter;

3. The sealing surface of the butterfly plate is made of hardfacing cobalt-based cemented carbide, which is wear-resistant and has a long service life;

4. Hard seal butterfly valve has simple structure, compact structure, light weight, easy installation and disassembly, and convenient maintenance;

5. The butterfly valve has a unique structure. The "switch" can be completed by turning the valve rod 90 °. The operation is flexible, convenient, labor-saving, not affected by the medium pressure, and the sealing performance is reliable;

6. High temperature, low temperature and corrosion resistance.

The new series GT pneumatic actuator is adopted, with double-acting and single-acting (spring return), gear transmission, safe and reliable; The large-diameter valve adopts series AW pneumatic actuator fork drive, with reasonable structure and large output torque, and has double-acting and single-acting

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

2. The cylinder is made of aluminum alloy, with light weight and beautiful appearance.

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

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

5. The actuator can select live signal feedback indication and various accessories to realize automatic operation.

6. IS05211 standard connection provides convenience for product installation and replacement.

7. The adjustable pitch screws at both ends can make the standard products have an adjustable range of ± 4 ° at 0 ° and 90 °. Ensure the synchronization accuracy with the valve.
