                  [Essential information]
                       Stainless steel vertical check valve depends on the flow of the medium itself to automatically open and close the valve, used to prevent the media back flow valve, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. Designed and manufactured strictly according to GB12235 standard, the valve plate is positioned along the center for lifting and moving. The Bush is made of special material with good abrasion resistance and small friction coefficient. The movement is flexible and reliable, and the sealing performance is excellent.

                  [Valve features]
                         H42W Stainless steel flange vertical check valve is in a closed state. Because of the pressure acting on the inlet end of the pipeline, the spring resistance is overcome so that the valve is opened. When the inlet end of the media pressure is lower than the exit end, the spring will push the spool to the valve seat, so that the valve closed, to prevent the flow of medium, so the beginning of the role of back. The stainless steel flange vertical check valve adopts the spring support valve core, so it can be installed vertically or horizontally.

                  [Adaptive condition]
                       Check valve installed in the pipeline system, the main role is to prevent media backflow, check valve is a kind of pressure on the media to open and close the automatic valve. The clip type check valve applies to nominal pressure PN1.0MPa~42.0MPa and Class150~25000; nominal diameter DN15~1200mm and NPS1/2~48; work temperature -196~+540℃ of various pipelines, used to prevent medium flow back. By choosing different materials, it can be applied to many mediums such as water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and uric acid.
