    Product Overview

    The two ends of the branch pipe of the swing check valve are welded structures, and the welded groove can be made according to standards or user requirements. It has advantages such as wear resistance, high temperature resistance, corrosion resistance, scratch resistance, and long service life. Suitable for pipelines of high-temperature and high-pressure water, steam, oil products, and superheated steam in thermal power plants, petrochemicals, metallurgy, and other industries with working pressure ranging from 1500 to 2500 and working temperature ranging from -29 to 570 ℃, as a device to prevent medium backflow.
