(API 624 Additional High Temperature Version)
Key Specifications / Features
The Bolted Bonnet Gate Valve is engineered to meet API 600 standards, ensuring high-quality performance and reliability. The valve features a cast carbon steel body made from ASTM A216 WCB material, providing robust durability and strength. With a nominal diameter of DN200 (8 inches) and a pressure rating of PN50 (Class 300 LB), it is designed to handle high-pressure applications. The raised face (RF) flanged ends facilitate secure and leak-free connections to piping systems.
