(API 624 Additional High Temperature Version)
Key Specifications / Features
We produce high-performance check valves that meet API 602 standards. These valves are forged from carbon steel ASTM A105N, ensuring robustness and durability. With a 1-inch (DN25) size and a pressure rating of Class 800 LB (PN130), they are designed for low emission and feature a bolted bonnet for enhanced safety and reliability. The socket welded ends provide secure and efficient connections. These check valves are ideal for applications requiring minimal leakage and reliable performance.
