Description
Gate gate valve with through knife DNOVA GVKRT3431N-2W-Fb-S DN50 Ru16 carbon steel, interflanged with hand wheel is designed for installation on the pipeline as a shut-off device and regulating the flow of medium with a high concentration of solid particles. It can also be used in gravity feed systems of solid and powdery substances, as the cutting edge of the knife allows cutting off high density flows.
