ASTM A995 6A Swing Check Valve, BS 1868, 8 Inch, CL1500, RTJ
Compliant with TA-LUFT/ISO 15848-1/API 624
(API 624 Additional High Temperature Version)

Key Specifications / Features

The ASTM A995 6A Swing Check Valve Plant produces high-quality swing check valves that adhere to API 6D and BS 1868 standards. These valves are made from duplex stainless steel, offering excellent corrosion resistance and mechanical strength. With an 8-inch (DN200) diameter and a Class 1500 LB pressure rating (PN250), they are designed for high-pressure applications. The valves feature a bolted bonnet for secure assembly and RTJ (ring-type joint) ends for reliable sealing.
