What is a Butterfly Valve?
Double Eccentric Butterfly Valve- Key features and Designs
Double Eccentric Butterfly Valve are available in several configurations, as standard configurations, the pressure rating is PN10, PN16 or PN25. BUTTERY VALVES SUPPLIERS IN EGYPT supply with three seat options: integral seat, changeable, stainless steel seat and stainless steel. As gearbox options Kevit Industrial Technologies Ltd offers IP67 and IP68 with handweel and position indicator. For buried application you can use IP68 for bir applications only and then they have IP67 and IP68 ISO flashes ready for actuators.
Double Eccentric Designs have a double offset with the stem located vertically and horizontally offset from the centre. Depending on the valve dimension the offset is 70-200 mm horizontal and 3- 5mm vertical offset.
Tilted Disc Design
The tension on the disc is released after a few degrees of opening giving:
- Reduced wear of the disc seal
- Low operating torques as the design minimises the compression of the sealing
By the fixated disc there is no play between dowels and shaft, this design results in no fluttering and gives a table disc during operation. Furthermore it extends the lifetime of the valve. Stainless steel drive dowels in each end.
- Shaft end zones protected against corrosion: Shaft ends fully encapsulated in disc, and fixed with dowels.
- Optimised Disc sealing: BUTTERFLY VALVES SUPPLIERS own rubber secures a reliable function
- The shape ensures fixation in correct position.
- Threaded holes in disc protected with O rings
- Bolt coated with precoat 80 to prevent any loosening
The seat can be an integral seat, it is a ductile iron seat integrated in the body, machine and epoxy coated. Or it can be a welded stainless steel seat, machined and polished to give a smooth surface. The stainless steel seat is also available in a replaceable seat variant from a BUTTERFLY VALVES SUPPLIERS EGYPT in a replaceable seat variant. Double shat sealing is replaceable under pressure.
Kevit’s double eccentric butterfly valves are approved and to sum up the feature the disc is titled to reduce wear and fixated to remove fling shaft ends are protected against corrosion and the disc ceiling is optimized coating.
