Model No. : 181102009

The API 6D Trunnion Ball Valve is a high-performance fixed ball valve designed for demanding oil and gas, petrochemical, and industrial pipeline applications. Manufactured to ASME B16.34 requirements, this 3-piece ball valve features an 18-inch (DN450) nominal size and 300 LB pressure class. Constructed from ASTM A216 WCB cast carbon steel, it provides excellent mechanical strength and reliable service performance. The full-bore design minimizes pressure drop and supports efficient media flow, while the raised face (RF) connection enables secure flange installation. As an API 6D trunnion-mounted ball valve, it offers dependable shutoff, durability, and operational stability for critical pipeline systems.
