KS- Unidirectional Knife Gate Valve


VAYCOM KS series knife gate valve has a monoblock cast body. It has a wafer design for installation between flanges. The standard model is for DIN PN10/PN16 and ANSI150 flanges; others are available on request. The slide is guided, and will thus be affected less by normal opening and closing operations. The gate is made of stainless steel AISI304/AISI316 polished, and the edges are rounded to extend the life of seals and gaskets.
