◆ Product overview: 

 American standard check valve is a type of valve designed, manufactured and tested in accordance with relevant U.S. standards to prevent fluid countercurrent. The American standard check valve relies on the pressure difference of the fluid itself to achieve automatic opening and closing. When the fluid flows in the normal direction, the pressure of the fluid pushes the valve disc to open, so that the fluid can smoothly pass through the valve and flow to the specified direction. When the fluid has a countercurrent trend, the countercurrent pressure will cause the valve disc to close quickly and close tightly to the seat to prevent the fluid from flowing backwards, thus protecting the equipment and media in the pipeline system from the influence of the countercurrent.
