Electric Actuated Butterfly Valve, API 609, DI, DN100, PN16

Product Name: Electric Actuated Butterfly Valve
Type: Concentric Butterfly Valve
Design Standard: API 609
Body Material: Ductile Iron
Size: DN100, 4 Inch
Pressure: PN16, Class 150 LB
End Connection: Double Flanged
Operation: Electric Actuator

The Wafer Concentric Butterfly Valve is designed to maintain a seal against bi-directional pressure differentials, preventing backflow in systems designed for unidirectional flow. It achieves this with a tightly fitting seal, gasket, O-ring, and precision-machined valve face on both the upstream and downstream sides of the valve. The valves feature threaded inserts on both sides of the valve body, allowing for installation into a system using two sets of bolts without the need for nuts. The valve is installed between two flanges, with a separate set of bolts for each flange. This design allows either side of the piping system to be disconnected without disturbing the other side.
