Product Name: Pneumatic Actuated Concentric Butterfly Valve
Design Standard: API 609
Body Material: ASTM A351 CF8
Size: 2 Inch, DN50
Pressure: Class 150 LB, PN16
End Connection: Wafer
Operation: Pneumatic Actuator
The Wafer Concentric Butterfly Valve is designed to ensure a bi-directional pressure seal, preventing backflow in unidirectional flow systems. It achieves this through a precision-machined valve face, tightly fitting seal, gasket, and o-ring. The valve body features threaded inserts on both sides, allowing installation with two sets of bolts without nuts. Positioned between two flanges, each side is secured with a separate bolt set, enabling one side of the piping system to be disconnected without disturbing the other.
