Description

A wafer-style butterfly valve fitted with a pneumatic actuator for automated on/off or throttling flow control. The compact wafer body installs between standard flanges and is available in a range of body, disc, seat, and shaft materials to suit various media. Nominal pressure ratings of PN10 and PN16 are supported across sizes DN50 to DN1200.
