Description
Knife Gate Valve DNOVA is intended for installation on a pipeline as a shut-off device and for regulating the flow of the working medium in water supply systems and the chemical industry. 1.3. 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.;
