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.
Selection notes
This knife gate valve is a bi-directional seal and unidirectional seal pattern, supplied for wafer, lug and flanged installation.
Sizes run DN50 to DN3000, in PN10, PN16.
Stated service media include coal, slag, sewage, paper pulp, pharmaceutical media and petroleum.
It is catalogued for Water & Wastewater, Oil & Gas and Industrial Process.
Built to MSS SP-81, API-598, BS PN10/PN16, DIN PN10 and DIN PN16.
