DF9A001 Concentric Flange Butterfly Valve Electric Actuator with Hand Wheel
DF9A001 is a concentric flanged butterfly valve with an integrated electric actuator and hand wheel, designed for on-off and throttling control in water, low-pressure industrial, and heating systems. It connects directly to pipe flanges using bolts, with the actuator providing automated operation and the hand wheel enabling manual override. The concentric disc design ensures low torque and smooth operation under repeated cycling.

- Automated isolation in power plant auxiliary systems during routine maintenance
- Centralised control of fire protection risers in high-rise buildings with remote monitoring
- Integration into SCADA systems for real-time flow management in municipal water distribution
Buyers It Suits
- EPC contractors sourcing automated valves for water and heating projects
- Plant engineers standardising on electrically operated butterfly valves across multiple sites
- System integrators installing remote control valves in HVAC and industrial process lines
- Valve distributors stocking electric actuated butterfly valves for retrofit and new builds
- Facility operators needing manual override capability on automated isolation points
How It Is Built
- Concentric disc design with central stem alignment for low torque and balanced operation
- Flanged end connection for direct bolt-up to pipe flanges
- Integrated electric actuator with built-in hand wheel for manual override
- Quarter-turn operation for fast on-off and throttling control
- Part of a product line covering DN10 to DN2600 and 0.05 to 4.0 MPa
- Designed for use in water, low-pressure industrial, and heating applications
Material Selection
- Body, disc, stem and seat materials are confirmed per order against the buyer's medium and temperature
- Seat and disc options follow the variants offered across the concentric flanged butterfly series
- Material certificates are issued with the order when the buyer requests them
How It Is Made
- Body casting inspected and machined on in-house fine machining equipment
- Disc and stem assembled with concentric alignment and tested for free rotation
- Electric actuator and hand wheel fitted and tested for full travel and torque
- Valve assembled, cycled, and pressure tested before packing
- Marked, wrapped, and crated for container shipment from Tianjin
How It Is Checked
- Dimensional check of flange bolt pattern and face-to-face length before assembly
- Actuator function and hand wheel operation verified on every unit
- Operating torque and full quarter-turn travel tested on each valve
- Testing carried out on the 10 sets of imported inspection and testing equipment
- Records maintained under the ISO 9001 quality management system
Certificates Issued With This Valve
- ISO 9001 quality management system certification
- ISO 14001 environmental management system certification
Certification statements are limited to the management system certificates the factory actually holds. Product-level approvals for your market are confirmed before order.
What Can Be Changed
- Actuator voltage and control signal type confirmed per the buyer's system requirements
- Hand wheel size and material selected based on site access and safety standards
- Flange drilling matched to the standard used on the buyer's pipework
- Private label marking and packaging available on OEM orders
- Mixed-diameter orders combined with other valves in one container for shipping
How It Compares With the Alternatives
| Concentric flanged butterfly valve with manual lever | The electric actuator enables remote control but adds cost and complexity; the lever is simpler and cheaper for low-frequency use |
|---|---|
| Lug type butterfly valve with actuator | The lug body allows end-of-line service; the flanged body requires flanges on both sides and cannot be used as a pipe end closure |
| Ball valve with electric actuator | The ball valve offers tighter shutoff at higher pressure but is more expensive and requires more space for actuator mounting |
| Gate valve with electric actuator | The gate valve provides full bore but is heavier, longer, and slower to operate; the butterfly valve is more compact and faster for throttling |
Installing and Operating This Valve
- Confirm the flange standard, bolt pattern, and actuator voltage before ordering
- Ensure the actuator is powered off and the hand wheel is disengaged before manual operation
- Tighten flange bolts evenly in a cross pattern to prevent body distortion
- Test actuator function and hand wheel override after installation and before pressurisation
- Do not use the flanged body as a pipe end closure during pressure testing
- Perform periodic manual cycling on valves that remain in one position for long periods

DF9A001 Concentric Flange Butterfly Valve Electric Actuator with Hand Wheel FAQ
What size and pressure rating is DF9A001?
It is available in nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. The exact rating is confirmed on request based on the buyer's line data.
Can this valve be used at the end of a pipe run?
No. A flanged butterfly valve requires pipe flanges on both sides to clamp against. For end-of-line service, consider the lug type body instead.
Which materials are used for the body, disc and seat?
Material selection depends on the medium and temperature on your line. We confirm the combination with the quotation and issue material certificates on request.
Can the actuator be replaced with a different type?
Yes. The actuator can be specified for different voltages, control signals, or types (pneumatic, electric) during the order process.
Is manual operation possible if power fails?
Yes. The hand wheel provides full manual override and can be used to operate the valve even when the actuator is not powered.
Do you supply the larger diameters in the same series?
Yes. The DF9A001 series continues through the larger nominal diameters, and our valve programme covers DN10 to DN2600 across all families.
What certification does the factory hold?
Tianjin MIC Valve Co., Ltd. is certified to the ISO 9001 quality management system and the ISO 14001 environmental management system.
