Named for their shape, knife gate valves have a sharp, knife-like gate that can cut through viscous or solid material in the flow. They are commonly used in wastewater treatment plants, paper mills, mining operations, and food industries, among others. Their primary function is to start or sop a flow or adjust its volume, but they do not control the pressure or flow rate.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003e\u003cspan\u003eMain technical characteristics of the gate valve DNOVA GVKR3131M-1W-Fb-S, body material - stainless steel AISI 304, knife material - stainless steel AISI 304, seal - METAL, handwheel operated\u003c\/span\u003e\u003c\/h4\u003e\n\u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"702\" style=\"border-collapse: collapse;
