GD341X Pipe-net butterfly valve
Overview
The butterfly valve uses a round butterfly plate turning along with the stem as the open-close part and is used mainly as a cutoff valve,also working with adjusting or cutoff and adjusting function.
Features

1. Small fluid resistance
2. Easy and quick and labor-saving open-close,which can be finished just with the butterfly plate rotating 90°.
3. The eccentric design makes the sealing face uneasily worn out and the butterfly valve long durable.
4. With the part material changed and paired,multiple media can be used.
