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.
