Butterfly valve’s working principle:


The disc fixes a shaft spin herewith the valve close or open. Leak tightness is provided between disc and seal.


  • Minimal loss of pressure
  • Easy to opening and closing
  • Good leak tightness
  • Compact design
  • Easy movement of the disk should be controlled during the assembling
  • Horizontal assembling should be preferred above DN300
