The Velan Type L high-temperature metal-seated ball valve is well suited for a variety of demanding services where high-temperature and abrasive solids are present.Unique, patented single-seat ball valve design. The Velan single-seat ball valve has a flat spring set acting through a hardfaced bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low delta P.
  • The design provides freedom for thermal expansion of the ball without jamming, even at extreme temperatures

  • Proven in qualification tests and field operation to be solids–proof, even for the toughest applications on slurry service with solids.
