CHECK VALVE：Check valves often called as non-return check valves or one-way valve, which is the valve that normally only allows fluid to flow forward one direction. Check valves have one entering port and one leaving port. MJ mainly according to standard of BS1868, ASME B16.34 and API 602 to provide check valves. According to other design standards, We provide you DIN and JIS check valves as well.

    MJ's Body of Check valves are made of metals. Such as: carbon steel, stainless steel and alloy steel, ect. Some other globe valves are made of special materials, such as Hastelloy steel、and special alloy. Transmitting and processing of media that are heavily corrosive, stainless steel check valves are usually selected to mitigate the problem for they can work well in the area with corrosive surroundings.

    Check valves are normally operated automatically without control of human beings or external force, thus needing no hand wheel or stem.

    For fit with the different inner pressures in the pipeline, Pressure seal check valves can adjust the pressure of sealing ring automatically. This type of check valves is usually used in high temperature and high pressure operating conditions.

    Check valves generally used in applications which have great demands of preventing pollution from backflow, such as keeping contaminated water from flowing back to water supply lines.
