Manufacturer: Econosto

Econ® ductile cast iron butterfly valve, wafer type with centric disc, one piece shaft supported by bronze radial bearings for smooth operation, rubber lined body. The rubber liner is vulcanized on a phenolic ring which forms a cartridge inserted in the body ensuring reduced torque and a long lifetime. This liner extends along the valve faces, eliminating the use of gaskets. The body with centering holes for easy pipe alignment is suitable for mounting between flanges according to DIN PN6/10/16 and ASME 150#. Face To Face dimensions are according to ISO5752/EN558 basic series 20, API 609, DIN 3202 K1 and BS 5155. The butterfly valve is provided with a handlever for manual operation. For easy mounting of both manual and automatic actuators the valve is executed with a topflange according to the ISO 5211 standard. Furthermore, this valve has an extended neck for isolation purposes and an external Epoxy coating for environmental protection of the body.
