Metal Seal Motorized Flange Butterfly Valves

DELCO stainless steel metal seal triple eccentric flange motorized butterfly valves are designed for remote control of media flow. The actuator uses an electrical current to open or close the valve. The butterfly valve operates with a disc that rotates, driven by the actuator, to either allow or restrict flow. These electrically controlled butterfly valves come in various sizes and with different seals, enabling you to select the most suitable option for your specific application.

Model: DK56-FB-G
Size Range: 2” to 20”
Pressure Range: 1.6MPa to 6.4MPa
Material: Stainless Steel 304/316
