Manual Welded Diaphragm Valve(SS handwheel)


  • 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


Working principle

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.
