The lug butterfly valves are widely applied, thanks to their multiple functions of regulation and on-off valves and they are a good solution whenever required compact dimensions and reduced weight. Thanks to the EPDM gasket and to the epoxy coating, the lug butterfly valves can be installed in drinking water plants. The lug butterfly valves are manufactured as centric type disc, they can stand both directions of fluid and are maintenance-free. The lug butterfly valves can be installed between welding neck flanges EN PN 10-16 and ANSI #150, without any need of additional flange gaskets. Such valves can be installed in any position. The lug butterfly valves come with lever (standard execution); reducing gear, pneumatic operator with single or double effect, electric actuator on request.
