The three-position SDV features a sealing method that uses regulated compressed air applied to the sealing rings, which results in an air-tight seal between the inlet and outlet ports. Features include: minimal line deflection and full port flow for low pressure drop; pipe or tube sizes from 2–6 in.; bi-directional (divert or converge); air and dust tight; used for pressure or vacuum applications; carbon (standard) or stainless steel product contact points.
