A CJ/T 219 control valve is an automated regulating valve manufactured in strict accordance with the Chinese Urban Construction Industry Standard (CJ/T 219), which dictates design, material, and testing specifications for hydraulic control valves utilized in municipal utility networks. Typically configured as a diaphragm-actuated globe or pilot-operated multi-functional valve, it automatically modulates its internal trim using the pipeline’s own fluid pressure to achieve precise pressure reduction, pressure relief, or water-hammer prevention. Fabricated from robust materials like GGG40 ductile iron or carbon steel, it features resilient EPDM or NBR seats to ensure a bubble-tight shutoff. Municipal infrastructure developers and water utility engineers can secure certified network pressure regulation by importing premium CJ/T 219 control valves directly from leading manufacturers in China through our commercial B2B platform.
