Product Detail  

Bronze internal thread vertical check valve


Principle action:

Check valve opening and closing parts rely on the flow of media and force to open or close, to prevent media backflow.Check valve is generally divided into lift, swing, butterfly, and the four types of horizontal general formula lift check valve should be installed in horizontal pipe road, vertical lift check valve and bottom valve is generally installed in vertical pipe, and the medium flows from bottom to top, swing check valve installation position is not restricted, and are normally installed in horizontal pipe, but also can be installed in vertical lines, or pour material on the pipeline.Note: Check valves allow media to flow in only one direction. Special attention should be paid to the direction of the media flow. The normal flow direction of the media should be consistent with the arrow direction indicated on the valve body, otherwise the normal flow of the media will be cut off.


H12W vertical screw check valve can be opened or closed by overcoming spring resistance due to the pressure of the medium at the inlet of the pipeline.When the medium pressure at the inlet end is lower than the outlet end, the spring will push the spool toward the valve seat and make the valve close, to prevent the medium counterflow, so the start-stop effect.Vertical check valve is widely used in chemical industry, liquefied petroleum gas, fluid, etc.
