8 inch 200mm PN16 manual type flanged cast iron rising stem sluice gate valve
Product Introduction
The gate valve is a kind of valve with opening and closing parts for the gate, and its direction of movement is perpendicular to the direction of the fluid, which can only be fully opened and closed, and cannot be adjusted and throttled.
Gate valves are sealed by the contact between the seat and the ram, and the sealing surface is usually overlaid with metal material to increase wear resistance.
Gate valves are widely used in pipelines, especially where large-diameter shut-off devices are required. Its advantages include small flow resistance, labor-saving opening and closing, water hammer phenomenon is not easy to generate, the medium can flow in any direction on both sides, compact structure, good manufacturing process, and wide range of application.
