(API 624 Additional High Temperature Version)
Key Specifications / Features
Our Extended Stem Gate Valve factory in China produces high-quality gate valves that meet API 600 standards. These valves feature a robust ASTM A216 WCB carbon steel body, ensuring durability and reliability in various industrial applications. With a DN200 (8-inch) size and a pressure rating of PN10 (Class 150 LB), they are designed for optimal performance under specified conditions. The valves come with RF (raised face) flanged ends for secure connections and are operated by a handwheel, providing easy control.
