ASTM B148 C95400 Concentric Butterfly Valve, API 609, 4 Inch

Key Specifications / Features

The ASTM B148 C95400 Butterfly Valve, supplied with a concentric type design, adheres to API 609 standards for reliable fluid control. With a 4-inch (DN100) size, Class 150 LB (PN20) pressure rating, and wafer ends, this valve offers secure, leak-tight sealing in various systems. Lever operated for ease of use, it provides efficient flow regulation.

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 achieves this with a tightly fitting seal, gasket, O-ring, and precision machining, featuring flat valve faces on both the upstream and downstream sides. The valve includes threaded inserts on both sides of the valve body, allowing installation 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 configuration enables either side of the piping system to be disconnected without disturbing the other side.
