Electric Actuated Flanged Butterfly Valve
Double Flanged · Electric Actuated · PN10/16 · Ductile Iron
Reguvale's Electric Actuated Flanged Butterfly Valve is a robust double-flanged butterfly valve designed for on/off isolation and modulating flow control in pipelines up to PN16. The valve is fitted with a reliable multi-turn electric actuator that accepts on/off or 4-20mA modulating signals, with a handwheel for manual override.
The body is ductile iron GGG50 with epoxy coating, the disc is SS304 (SS316 and duplex options available), and the seat is replaceable EPDM/NBR/Viton to match the medium. The double-flanged design allows direct mounting between PN10/PN16, ANSI 150, and JIS 10K flanges without extra adapters. Each valve is assembled and pressure-tested at our Tianjin factory before shipment.
Actuator voltage (24VDC / 110VAC / 220VAC / 380VAC), control type (on/off or modulating), and feedback options can be configured to suit your automation system.

Frequently Asked Questions
What is an electric actuated flanged butterfly valve used for?
An electric actuated flanged butterfly valve is used for remote on/off isolation and flow modulation in pipelines that require automation. Common applications include water treatment plants, HVAC systems, power generation, mining slurry lines, and industrial process control.
Can the electric actuator be supplied with a manual override?
Yes. Reguvale electric actuators are supplied with a handwheel for manual override in case of power failure or maintenance, allowing local operation even when the motor is de-energized.
What control signals are available for the electric actuator?
Standard actuators accept ON/OFF control (24VDC, 110VAC, 220VAC, 380VAC). Modulating 4-20mA input/output, position feedback, and bus-protocol options are available on request.
