Mono flanged butterfly valve, type 1130

This concentric mono flanged valve, is suitable for mounting between flanges and can be used in many general applications such as in water distribution, water treatment, dams, power plants and in many other. The valve can be used as a stopper, a tap for discharging at the end of the pipeline, open/close and flow control. The threaded holes make it easy to install or uninstall from the pipeline. Operation can be manual, pneumatic, hydraulic or electric.
