J41 (Y / h) American Standard stop valve
purpose:
Stop valves are widely used in petroleum, chemical, food, medicine, metallurgy and other industries as cut-off and regulating equipment due to their advantages of good quality and low price. Especially, with their unique structural form, they are easy to control the accuracy of regulation. Therefore, it is a good choice to select regulating stop valves to regulate the flow
Product features:
Stop valve is also called shut-off valve. Its opening and closing parts move up and down along the center line of the sealing surface of the valve seat to open and close the valve. Its path is perpendicular to the seal, so there is no friction on the sealing surface during opening and closing, and its service life is long.
