Abstract
Embodiments of the invention provide a knife gate valve for flow along a flow path. The knife gate valve can include a body structure that includes a gate passage, a gate disposed to move within the gate passage between open and closed positions to selectively open or close a fluid aperture, and a gate seat configured to engage a free end and lateral edges of the gate. A transverse element can be formed from resilient material and can extend laterally across the gate passage to form a seal with a first side of the gate and with the gate seat.
