Flanged butterfly valve with double eccentric complete with manual or electric actuator Pn 10

Flanged ductile iron double eccentric butterfly valves PN 10 are shut-off and control devices used in pipeline systems to control the flow of liquids. Their design includes a disc that rotates a quarter turn (90 degrees) around its axis to open or close the flow. Double eccentric means that the disc axis is offset from the body center in two directions. This reduces contact between seal and seat during operation, reducing wear and ensuring a longer service life.

Applications

Double eccentric butterfly valves are widely used in various industrial and municipal systems:

1. Water supply:
   • They are used to transport water.
2. Wastewater treatment plants:
   • They are used at water treatment plants and pumping stations to regulate water flows.
3. Industry:
   • They are used in cooling systems at power plants.
4. Tanks and tanks:
   • They provide hermetically sealed shut-off of liquid flows in tanks for various purposes.

Design advantages

1. Durability:
   • Minimum friction between seal and seat increases the service life of the device.
2. Low operating moments:
   • Design reduces effort required to open/close the valve.

These butterfly valves can be equipped with a manual actuators or an electric actuators.
