Highlight: Flanged diaphragm valve
Product introduction:
A diaphragm valve is a special type of valve with a shut-off function. Its closing part consists of a steel valve
disc and a diaphragm made of soft materials (a composite of rubber and fluoroplastic), which separates the
inner cavity of the valve body from the inner cavity of the valve cover, so as to achieve the purpose of
shutting off the medium in the pipeline.

Product features:
1. Elastic-sealed opening and closing parts ensure no internal leakage.
2. The streamlined flow channel results in small pressure loss.
3. There is no stuffing box, so there is no external leakage.
4. The valve body and the cover are separated by an intermediate diaphragm, so that parts such as the
valve cover and valve stem above the diaphragm are not eroded by the medium.
5. The diaphragm can be replaced, resulting in low maintenance costs.
