productspipe fittings, valves, aseptic diaphragm valves, aseptic tank bottom valves and other high-end products
- suitable for inert and corrosive liquid and gaseous media
- support cip/sip
- pasteurized
- valve body and diaphragm are available in a variety of materials
- stepless minimum flow regultion by hermetic regulator
the diaphragm is close under normal state,and that moment the diaphragm clung to the valve body cavity,
and closing off the flow path through the pipeline.when the diaphragm valve have the requirement to clean
or open,the valve stem moves upwards according to the manual or pneumatic actuator equipment,spherical
diaphragms naturally bend upwards ,so that the valve is open and reach the requirement of clean and open.
the diaphragm make the lower body cavity and the uppper chamber separated from the valve cover,so that
the stem at the top of the diaphragm,disc media and other parts from corrosion,eliminating the need for packing
structure,and no media leaks.the optimize valve body made the cleaning liquid flow out totally ,so that don't have
any entrapment.
