1. The biggest difference between the fluorine-lined diaphragm valve and other valves is that it adopts a structure without a stuffing box; the fluorine-lined diaphragm valve diaphragm can completely isolate the corrosive medium in the flow path from all driving parts, thereby eliminating the usual valve The disadvantages of “running, risking, dripping, leaking” and so on.

Refer to straight through type DIAPHRAGM VALVES

1）DN 25, DN 32, DN 40, handwheel+bonnet+compressor+spare diaphragm totally same, size and shape and others are all same. But body different.
 
2） DN65 and DN80,  handwheel+bonnet+compressor+spare diaphragm totally same, size and shape and others are all same. But body different.

The valve stem of the diaphragm valve is sealed by a soft and pressure-bearing diaphragm that connects the valve stem to the closing member. As long as the diaphragm does not fail, this seal can prevent any medium from leaking to the atmosphere through the valve stem. The shape of the diaphragm can be a round cap shape or a bellows shape. The material structure of the diaphragm. Depending on the application, it can be made of rubber elastomer and plastic.
