PRODUCT DETAILS
The D671X Pneumatic Wafer Butterfly Valve is a compact, soft-seated valve designed for automated isolation and flow control in commercial and industrial pipeline systems.
Its wafer-style body is installed between pipeline flanges, helping reduce installation space, overall weight, and material requirements compared with conventional flanged butterfly valves. The centerline concentric design provides simple quarter-turn operation, low flow resistance, and reliable sealing for compatible media.
The pneumatic actuator provides fast and reliable automated operation. Double-acting and spring-return configurations are available, allowing the valve to be selected for standard on/off control or fail-safe applications according to project requirements.
