Description
A knife gate valve available in two configurations: a bi-directional seal variant with ductile iron body and stainless steel wedge using a U-shaped flexible seal without grooves, and a unidirectional seal variant with an additional bonnet design suitable for high-pressure applications. Both types are designed for handling slurries, fibrous media, sewage, and other demanding industrial fluids. The bi-directional variant uses a wafer-type body while the unidirectional variant is available in wafer, lug, and flanged end connections.
