The knife gate valves up to DN 700, are built with a one-piece body that can be made of cast iron or stainless steel. The blade is made of 304 stainless steel polished to a mirror finish on both sides to guarantee a watertight seal with the gasket. The sides of the blade are rounded to avoid cutting the gasket. The gasket can be EPDM or NBR rubber, a strip of the gasket is greased to facilitate operation during opening and closing of the valve.
Knife gate valves are easily replaceable as they are located in an area that can be reached without having to dismantle the valve from the line. The shaft is made of stainless steel with the thread rolled up. All parts are protected from corrosion by epoxy paint.
