The Knife Gate Valve is a uni-directional wafer valve for general industrial application.It is predominantly used in the
paper and pulp
power station technology industry
sewage treatment plants
steel industry and
animal feed sectors
The nominal widths available range from DN50 to DN1200 with flange connections complying with EN 1092 PN10 or alternatively, ANSI B16.5 (class 150).
The structure of the unidirectional Knife Gate Valves encompasses a so-called wafer style cast monoblock body, with raised face and reinforced ribs for larger nominal diameters for extra body strength.
The monoblock body is available in either grey cast iron (GG25) or alternatively in stainless steel AISI 1.4408 (CF8M).
The slide plate is manufactured using stainless steel AISI 304 or AISI 316 as standard. The plate radius of the slide gate has a bevelled cutting edge. As a result, solids can be cut through, achieving a tight seal in the closed position. On request, the thickness of the Knife Gate Valves plate can be increased for higher operating pressures and/or higher quality material can be used.
