Lock Slag Ball Valve

  • Split-type body and trunnion ball design, to avoid excessive pressure on the valve seat and damaged seat.
  • The ball and the valve stem are designed and processed in an integrated manner to ensure the ball and stem in the centre line of valve, and avoid the valve stem disengagement by the frequent opening.
  • Used Inconel X-750 spring or high temperature resistant Viton
  • The valve seat has the self-scraping function then realize the self-cleaning of the spherical surface
