Appendix 1. The biggest difference between the diaphragm valve and other valves is that it adopts a structure without a stuffing box; the rubber diaphragm can completely isolate the corrosive medium in the flow channel from all the driving parts, thereby eliminating the usual “running,” Drawbacks, drips, leaks, etc.
Appendix 2. Since the flow path of the diaphragm valve is smooth and the flow resistance is small, a larger flow rate can be obtained.
Attachment 3. There are many kinds of rubbers for selection on the surface of the inner cavity of the rubber diaphragm valve. Therefore, it has superior corrosion resistance.
Appendix 4. Because the seal is a flexible rubber diaphragm. Therefore, it also has better sealing and minimum closing force.
