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 the liquid accumulation at the pipe mouth is the least.

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. The operation is flexible and labor-saving, and manual, electric, pneumatic and hydraulic methods can be selected.

Product Cons:

1. The operating pressure and working temperature range are small.

2. Poor sealing.

Butterfly valve can be divided into offset plate type, vertical plate type, inclined plate type and lever type according to the structure.

According to the sealing form, there are two types of soft sealing type and hard sealing type. The soft seal type is generally sealed with a rubber ring, and the hard seal type is usually sealed with a metal ring.

According to the connection type, it can be divided into flange connection and wafer connection; according to the transmission mode, it can be divided into manual, gear transmission, pneumatic, hydraulic and electric.
