Pneumatic quick-install butterfly valve is a kind of regulating valve with simple structure, which can be used for on-off control of low-pressure pipeline medium. valve. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

Features

1. Butterfly valve has the characteristics of simple structure, small size, light weight, low material consumption, small installation size, rapid switching, 90° reciprocating rotation, small driving torque, etc. It is used to cut off, connect, and adjust the medium in the pipeline. Offers good fluid control properties and shut-off sealing.

2. The butterfly valve can transport mud, and there is less liquid accumulated at the pipe mouth. At low pressure, a good seal can be achieved. Good adjustment performance.

3. The streamlined design of the butterfly plate makes the loss of fluid resistance small, which can be described as an energy-saving product.

4. The valve stem is a through-rod structure, which has been quenched and tempered, and has good comprehensive mechanical properties, corrosion resistance and scratch resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up and down, the packing of the valve stem is not easy to be damaged, and the sealing is reliable. It is fixed with the cone pin of the butterfly plate, and the overhanging end is designed to prevent the valve stem from breaking out when the connection between the valve stem and the butterfly plate is accidentally broken.

5. The connection methods include flange connection, wafer connection, butt welding connection and lug wafer connection.

product advantages

1. The opening and closing is convenient and quick, labor-saving, and the fluid resistance is small, which can be operated frequently.

2. Simple structure, small size, short structure length, small volume and light weight, suitable for large-diameter valves.

3. The mud can be transported, and there is less liquid accumulated at the pipe mouth.

4. Under low pressure, good sealing can be achieved.

5. Good adjustment performance.

6. When fully open, the effective flow area of the valve seat channel is larger and the fluid resistance is smaller.

7. The opening and closing torque is small, because the discs on both sides of the rotating shaft are basically equally affected by the medium, and the direction of the torque is opposite, so the opening and closing is more labor-saving.

8. The sealing surface material is generally made of rubber and plastic, so the low pressure sealing performance is good.

9. Easy to install.

10. Flexible and labor-saving operation, manual, electric and pneumatic can be selected.
