(API 624 Additional High Temperature Version)
Key Specifications / Features
This ASTM A217 WC6 Check Valve is manufactured in compliance with API 6D and BS 1868 standards, offering robust backflow prevention for high-pressure systems. Constructed from alloy steel for excellent heat and pressure resistance, it features a 20-inch (DN500) size, Class 600 LB (PN100) rating, and a swing disc design for reliable one-way flow. The valve includes a bolted bonnet for secure sealing, low emission performance, and raised face (RF) ends for strong, leak-tight connections in power, oil, and gas applications.
