DF9A002 Concentric Flange Butterfly Valve Electric Actuator DN1200
DF9A002 is a DN1200 concentric flanged butterfly valve with an integrated electric actuator, designed for on-off and throttling service in medium- and low-pressure water, heating, and industrial process lines. The flanged body connects directly to pipe flanges with bolts, and the electric actuator enables remote or automated operation without manual effort. The concentric disc design ensures low torque and smooth flow control, suitable for systems requiring reliable, repeatable operation over time.

What This Model Gives You
- Electric actuator enables remote or automated control without manual intervention
- Flanged connection allows direct bolt-on installation to existing pipe flanges
- Concentric disc design provides low operating torque and smooth flow regulation
- DN1200 size fits large-diameter pipelines in water, heating, and industrial systems
- Integrated actuator reduces need for separate mounting hardware or control accessories
- Part of a valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Manual operation of large DN1200 valves is physically demanding and slow in high-frequency service
- Lack of automation leads to inconsistent valve operation and delayed response during system changes
- Separate actuator mounting requires additional space, alignment, and installation time
- Inconsistent valve positioning in remote or high-traffic areas leads to operational errors
- Buyers need a single supplier who can deliver both large valves and their actuation systems
Where It Is Installed
- Remote isolation of large water supply lines in municipal distribution networks
- Automated throttling control in district heating systems with variable flow demand
- On-off control of process water in petrochemical and chemical plant feed lines
- Centralised valve management in power plant auxiliary systems with remote monitoring
- Large-diameter pipeline isolation in sewage treatment plant flow control stations
Buyers It Suits
- Utility and municipal engineers sourcing large-diameter automated valves for water and heating systems
- EPC contractors integrating automated valves into large-scale industrial projects
- Plant operators needing remote control of DN1200 valves in high-traffic or hard-to-reach locations
- Valve distributors stocking automated butterfly valves for large-diameter applications
- Facility managers standardising on electric actuated valves across multiple pipeline systems
How It Is Built
- Flanged connection with bolt holes matching standard flange patterns
- Concentric disc design with central stem for balanced torque and low resistance
- Integrated electric actuator for remote or automated operation
- Quarter-turn operation with actuator-driven stem rotation
- Part of a concentric flanged butterfly valve series covering DN10 to DN2600
- Suitable for on-off and throttling duty in water, heating, and low-pressure industrial services
Material Selection
- Body, disc, stem, and seat materials are confirmed per order based on the medium and operating temperature
- Seat and disc variants follow the options available in the concentric flanged butterfly series
- Material certificates are issued with the order upon request
How It Is Made
- Body casting inspected and machined on in-house fine machining equipment
- Disc and stem assembled with concentric alignment and fitted to the actuator interface
- Electric actuator mounted and tested for full travel and torque output
- 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 operation verified for full quarter-turn travel and torque consistency
- Seat and shell tightness tested on the assembled valve
- Testing performed 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
- Seat and disc variant selected based on the medium and temperature on the buyer's line
- Flange drilling matched to the standard used on the buyer's pipework
- Electric actuator configured for voltage, signal type, and control interface as required
- Private label marking and packaging available on OEM orders
- Mixed-diameter orders combined with other valves in one container
How It Compares With the Alternatives
| DN1200 manual flanged butterfly valve | The manual version requires physical effort to operate; the electric actuator enables remote or automated control without operator fatigue |
|---|---|
| DN1200 gate valve | The gate valve provides a full bore but is heavier, longer, and more complex to install; the butterfly valve offers a compact, lightweight alternative |
| DN1200 lug type butterfly valve | The lug body allows end-of-line service; the flanged body requires flanges on both sides but offers more secure bolted connection |
| DN1200 ball valve | The ball valve offers tighter shutoff at higher pressure but costs more and requires more space for actuator mounting |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe flanges before ordering
- Ensure the electric actuator is powered and connected to the control system before first operation
- Check that the actuator is set to the correct travel limit and direction before commissioning
- Perform a manual override test to verify the valve can be operated in case of power failure
- Do not operate the actuator if the valve is obstructed or under pressure from both sides
- Schedule periodic checks of actuator function and valve position feedback in automated systems

DF9A002 Concentric Flange Butterfly Valve Electric Actuator DN1200 FAQ
What size and pressure rating is DF9A002?
It is a DN1200 valve in the DF9A002 concentric flanged butterfly series. The pressure rating and flange standard are confirmed against your line data when we quote, since the same body is offered in multiple variants.
Can this valve be used at the end of a pipe run?
No. A flanged body requires pipe flanges on both sides to bolt against. For end-of-line service, ask for a 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, so we confirm the combination with the quotation and issue material certificates with the order on request.
Can the actuator be replaced or upgraded later?
Yes. The actuator is mounted on the valve stem and can be removed and replaced with another type, provided the interface matches the original design.
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.
How do I get a quotation?
Send the model, quantity, flange standard, medium, and actuator requirements by WhatsApp or email and our sales engineers reply with a quotation and a confirmed specification sheet.
Do you supply the larger diameters in the same series?
Yes. The concentric flanged butterfly valve programme continues through the larger nominal diameters, and our valve programme covers DN10 to DN2600 across all families.
