Usage and Features:
The metal-to-metal butterfly valve realize veritable zero leakage bu installing and elastic seal ring of stainless steel on the body:
Adjustable seal, lifetime of 100,000 times without leakage
Special seal structure: Seal won't be deformed with the force, with no leakage under high temperature and cold condition
Three-eccentric structure, separated if open and sealed if closed
It solves the wearing problem of seal faces to avoid seay leakage by axial positioner, and the actuator can be installed at any direction
It is applicable to the cleaning pipelines of foodstuff, pharmacy, petrochemical industrial, Industrial Environment protection, Water Solution, high building and water treatment, supplying and drain pipelines as open/closed function or adjust the flow.
