VAAS - Valves with a Leading Edge

Knife gate valves are generally uni-directional valves; however, in some application situations, valves are required to handle pressure or flow from either directions. Bi-directional designs are used in such situations. VAAS offers a range of bi-directional gate valves for such requirements
Unlike uni-directional knife gate valves, bi-directional valves are always resilient seated; VAAS offers a design that uses a U-shaped elastomer seal that provides a peripheral seal along the edge of the gate. There is no raised seat in the flow path and in the open position these valves offer maximum flow area and minimum resistance to flow (and lowest pressure drop)
