Definition

The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing. a kind of valve.

Advantages

1. It is convenient and quick to open and close, labor saving, small fluid resistance, and can be operated frequently.

2. simple structure, small size, short structure length, small size, light weight, suitable for large diameter valves.

3. under low pressure, can achieve a good seal.

4.  the adjustment performance is good.

5.  The valve seat channel has a large effective flow area and a small fluid resistance when fully opened.

6.  The opening and closing torque is small. Since the butterfly plates on both sides of the rotating shaft are basically equal by the medium, the torque is generated in the opposite direction, so the opening and closing is relatively labor-saving.

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

8.  easy to install.

9. Flexible and labor-saving operation, manual, electric, pneumatic and hydraulic modes are available.

The valve is small in size, light in weight, compact in structure, quick in opening, reliable in sealing performance, light and labor-saving, long life and easy to maintain.
