(API 624 Additional High Temperature Version)
Key Specifications / Features
The API 623 Globe Valve Plant in China offers high-quality 16-inch (DN400) globe valves designed to meet stringent industry standards. These valves are manufactured from cast carbon steel (ASTM A216 WCB) and adhere to BS 1873 specifications. They feature a robust bevel gear mechanism for reliable operation and are rated for Class 300 LB and PN50 pressure classes. The valves have raised face (RF) ends and metal-seated construction, ensuring durability and performance in demanding industrial applications.
