Product Name: PTFE Lined Butterfly Valve
Design Standard: API 609
Body Material: ASTM A216 WCB
Size: DN100, 4 Inch
Pressure: PN16, Class 150 LB
End Connection: Flanged
Operation: Gearbox
The Wafer Concentric Butterfly Valve is designed to maintain a seal against bi-directional pressure differentials, preventing backflow in systems intended for unidirectional flow. It features a tightly fitting seal, gasket, O-ring, and precision-machined flat valve faces on both the upstream and downstream sides. The valve body includes threaded inserts on both sides, allowing installation into a system using two sets of bolts without the need for nuts. This design enables the valve to be installed between two flanges, with separate bolt sets for each flange, allowing either side of the piping system to be disconnected without affecting the other side.
