H71 Wafer Type Single Dsic Lift Check Valve

Check valve, also known as non-return valve, its function is to prevent media backflow in the pipeline. The bottom valve of the pump suction close also belongs to the check valve category. The opening and closing parts are opened or closed by the flow and force of the medium to prevent the backflow of the medium from being called a check valve.
Product Details


            The disc slips along the vertical center line of the valve body. The lift check valve can only be installed on the horizontal pipe, and the disc can use a ball on the high pressure small caliber check valve. The valve body of the lifting check valve is the same as the globe valve (which can be used with the globe valve), so its fluid resistance coefficient is large. The upper part of the disc and the lower part of the cover are machined with a guide sleeve, and the disc guide can be lifted and lifted freely in the guide simple of the valve. When the medium flows down, the disc is opened by the medium thrust, and when the medium stops, the disc falls on the seat from drooping, which plays the role of preventing the media countercurrent. The direction of the medium inlet and outlet channel of the straight lift check valve is perpendicular to the direction of the valve seat channel, and the direction of the medium inlet and outlet channel of the vertical lifting check valve is the same as that of the valve seat channel, and its flow resistance is smaller than that of the straight way.
