Telescopic butterfly valve
The retractable butterfly valve has a simple structure, small size and light weight and is composed of only a few parts. And only need to rotate 90 degrees to open and close quickly, the operation is simple, at the same time the valve has good fluid control characteristics.
When the telescopic butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is very small, so it has better flow control characteristics. The butterfly valve has two types of seals: elastic seal and metal seal. Elastic sealing valve, sealing ring can be mounted on the valve body or attached around the butterfly plate.
The retractable butterfly valve is mainly divided into a flange type butterfly valve and a wafer type butterfly valve. The wafer type butterfly valve uses a double head bolt to connect the valve between two pipe flanges. The flange type butterfly valve has a flange on the valve and uses bolts. Connect the upper flange of the valve to the pipe flange.
