ASTM A351 CF8 Butterfly Valve, API 609, 2 Inch, CL150, Wafer

Product Name: Wafer Concentric Butterfly Valve
Design Standard: API 609
Body Material: ASTM A351 CF8
Seal Material: PTFE
Size: 2 Inch, DN50
Pressure: Class 150 LB, PN20
End Connection: Wafer
Operation: Lever

The Wafer Concentric Butterfly Valve is designed to maintain a reliable seal against bi-directional pressure differentials, preventing backflow in systems that are intended for unidirectional flow. It achieves this with a precisely fitting seal, gasket, and o-ring, all precision-machined for accuracy, and features flat valve faces on both the upstream and downstream sides. The valve body includes threaded inserts on both sides, enabling installation using two sets of bolts without the need for nuts. This design allows the valve to be installed between two flanges with a separate bolt set for each flange, enabling either side of the piping system to be disconnected without disturbing the other.
