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

Product Name: PFA Lined Butterfly Valve
Design Standard: API 609
Body Material: ASTM A216 WCB
Size: 2 Inch, DN50
Pressure: Class 150 LB, PN20
End Connection: Wafer
Operation: Gearbox

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.
