EMEB-OCF Electric actuated flanged butterfly valve by em-flow the optimal automation solution for any system
The EMEB-OCF Electric actuated flanged butterfly valve is a premium automated control valve from the brand EM-Flow (Taiwan), engineered for precise and efficient flow control in pipelines. By utilizing an electric actuator to rotate the valve disc, this product enables fully automated on/off or modulating control of fluids.
Featuring a standard flange connection, the EMEB-OCF valve ensures easy, secure, and leak-proof installation. It stands as the ideal choice for industries that demand stability, durability, and a high degree of automation.
EM-Flow EMEB-OCF
Detailed technical specifications:
Model: EMEB-OCF
Brand: EM-Flow
Origin: Taiwan
Size: DN40 – DN600
Body Material: Cast Iron (WCB)
Disc Material: Stainless Steel 304 (SUS304) / Cast Iron (WCB)
Understanding its construction and operation reveals the superior capabilities of the EMEB-OCF valve.
Main Components
Body: Cast from robust materials like iron, carbon steel, or stainless steel, providing high strength and pressure resistance. The flange design allows for a direct and sturdy connection to pipelines using bolts.
Disc: The core component that controls the flow, typically made from stainless steel (SS304/SS316) for excellent corrosion and abrasion resistance. The disc rotates 90° to open or close the valve.
Stem: A durable metal shaft, made of stainless steel, that connects the electric actuator to the disc, transmitting rotational force to operate the valve.
Seat: An elastomeric ring (EPDM, NBR, PTFE) fitted between the disc and the body. It ensures a bubble-tight seal when the valve is closed, preventing any leakage.
Electric Actuator: The “brain” of the valve, which converts an electrical signal into mechanical rotational motion. EM-Flow’s actuators are renowned for their durability and precision.
Operating Principle
Upon receiving an electrical signal from a control panel or PLC, the motor inside the electric actuator is energized. Through a gearbox system, the motor generates powerful torque, which rotates the valve stem 90°. This action turns the disc to either the fully OPEN or fully CLOSED position, allowing or blocking the fluid flow.
For modulating versions, the opening angle of the disc can be precisely adjusted based on an analog signal (4-20mA or 0-10V), enabling accurate flow rate regulation.
Outstanding features of the EMEB-OCF electric butterfly valve

I purchased this valve for a new industrial water line, and I am mostly impressed. The build quality is top-notch, feeling very robust and durable. The actuator is quiet and precise, opening and closing the valve smoothly. My only minor critique is that the wiring diagram in the manual could be more detailed, but I was able to figure it out. Overall, a solid and dependable choice for heavy-duty applications.
