PFA Lined Butterfly Valve, API 609, A216 WCB, 2 Inch, CL150

Key Specifications / Features

The PFA Lined Butterfly Valve is engineered according to API 609 standards, featuring a carbon steel ASTM A216 WCB body. With a 2-inch (DN50) size, it operates within a pressure class of 150 LB and PN20, offering excellent durability and performance. Its wafer ends ensure easy installation, and the PFA lining provides superior chemical resistance, making it ideal for various industrial applications.

The Wafer Concentric Butterfly Valve is designed to maintain a reliable seal against bi-directional pressure differentials, preventing backflow in systems intended for unidirectional flow. It achieves this through a precisely fitted seal, gasket, and O-ring, along with precision machining and a flat valve face on both the upstream and downstream sides. The valve features threaded inserts on both sides of the body, allowing for installation using two sets of bolts without the need for nuts. It is mounted between two flanges, with each flange secured by a separate set of bolts. This configuration enables either side of the piping system to be disconnected without affecting the other.
