Econ® ductile iron butterfly valve, double-flanged type with centric disc, one piece

shaft supported by bronze radial bearings for smooth operation, rubber lined body.

The rubber liner is vulcanized integrally to body and bearings ensuring reduced torque

and a long lifetime. This liner extends along the valve faces, eliminating the use of

gaskets. The double flanged body is suitable for mounting between flanges according

to DIN PN 10 or PN 16. Face to face dimensions are according to ISO5752/EN558

basic series 13, DIN 3202 F16 and BS 5155. For easy adaption of both manual and

automatic actuators the valve is executed with a topflange according to the ISO 5211

standard. Applications of series 46 butterfly valves can be found amongst others in

general industrial and maritime systems for media such as (ballast) water, gases,

hydrocarbons and light corrosive media up to a maximum of 16 bar (PN 16 execution).
