The check valve is automatically opened and closed by the force of the flow of the medium itself in the pipeline, which belongs to an automatic valve.Check valves are used in piping systems to prevent backflow of media and release of media from containers.Check valves can also be used in piping where pressure may rise above the primary system pressure to supply the secondary system.
Check valve application suggestions:
1.The check valves are threaded to the end of the pipe where the internal thread is cylindrical and the external thread must be tapered.During installation, wrench the hexagon position on the same side of the thread, do not wrench the hexagon position on the other end of the check valve, so as not to cause deformation of the check valve.
2.When the check valve is used for saturated steam, the saturated steam pressure is no more than 0.6mpa.
