Featuresing interior bellows designing,avoid erosion and washing out,ensure maximum life expectancy;Position limited design when the valve turn on, increasethe sealing on the top stem.Multilayer structure sealed, the capability can be more credible.summaryGlobe check valve can open and close the disc automatically depend on the medium itself flowed, using as prevent medium flow backwards,prevent pump of its drive reversing and the medium leaked out from the container. Check valve also can use for present pressure ability exceed main system pressure of assistant system offer replenishment of the pipeline; When used in the boiler, depend on the medium pressure, can on-off quickly, ensure the safely for the boiler working.
