Application

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.
The butterfly valve's disc is mounted in the diameter direction of the pipe. The butterfly valve is simple in structure, small in size and light in weight. It consists of only a few parts, and can be quickly opened and closed by only rotating 90°. The operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.

Strength

1. The butterfly valve can transport the mud and accumulate the least amount of liquid at the pipe mouth. A good seal can be achieved at low pressure. The adjustment performance is good.
2. The streamlined design of the butterfly plate, the fluid resistance loss is small, can be described as an energy-saving product.
