Wafer soft seal butterfly valve

Commonly used butterfly valves include wafer butterfly valves and flange butterfly valves. Wafer-type butterfly valves use studs to connect the valve between two pipe flanges. Flange-type butterfly valves have flanges on the valve, and bolts are used to connect the flanges at both ends of the valve to the pipe flanges.

The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve opening, closing or adjustment. The universal valve is called a butterfly valve. The range from fully open to fully closed of a butterfly valve is usually less than 900. The butterfly valve and butterfly rod themselves do not have self-locking force. In order to position the butterfly plate, a worm gear reducer must be installed on the valve rod. The use of worm gear reducer not only makes the butterfly plate self-locking, allowing the butterfly plate to stop at any position, but also improves the operating performance of the valve.

The advantages of programmable switch butterfly valve: easy and fast opening and closing, labor saving, small fluid resistance, and can be operated frequently. It has simple structure, small size and light weight. Slurry can be transported with minimal liquid accumulation at the pipe mouth. At low pressure, good sealing can be achieved. Good adjustment performance.
