Introduction of check valve


Check valve, also known as one-way valve or check valve, its role is to prevent the backflow of media in the pipeline. Includes swing check valve and lift check valve. Swing check valves have a hinged mechanism and a door-like disc that rests freely on the inclined seat surface.

Special valve selection matters needing attention


Most of the fluid media used in the process industry involve oil and gas streams of different corrosive grades. These flow conditions, including medium flow, are considered to be either clean, dirty, or worn (mud conditions), and the difference lies mainly in the number and type of solid suspended particles that cause valve blockage or corrosion damage.
