The principle of operation of the gate valve is to move the gate (knife) perpendicular to the flow of the medium. When the nominal diameter of the pipeline is completely blocked, a stop occurs flow, with partial flow - adjustment. The tightness of the gate valve in the closed state is ensured by pressing the gate valve to the seal under the influence of the pressure of the working medium.;\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eMain technical characteristics of the gate valve DNOVA GVK3131M-1W-Fb-2P, wafer
