DE9D002 Double Eccentric Flange Butterfly Valve Resilient Seat and Electric Actuator
DE9D002 is a double eccentric flanged butterfly valve with a resilient seat, fitted with an electric actuator for automated on-off control. It is designed for medium- and low-pressure service in water, heating, and industrial process lines. The double eccentric design reduces seat wear and enables smooth operation with low torque. The electric actuator allows remote or automated operation via control signals, making it suitable for integration into process control systems.

What This Model Gives You
- Double eccentric design minimises seat wear and extends service life under frequent cycling
- Resilient seat provides reliable bidirectional sealing at low to medium pressure
- Electric actuator enables remote or automated operation without manual intervention
- Flanged connection allows secure mounting to pipe flanges with standard bolting
- Low operating torque reduces actuator size and power consumption
- Part of a valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Manual valves are slow to operate and not suitable for remote or frequent control
- Frequent cycling causes seat wear and leakage in standard butterfly valves
- Lack of actuator integration requires separate installation and wiring
- Valves with high torque demand larger actuators and higher power draw
- Inconsistent valve performance across different operators leads to operational errors
Where It Is Installed
- Automated isolation of water supply lines in district heating plants with central control
- Remote shut-off on process water headers in chemical and pharmaceutical facilities
- Integration into SCADA systems for monitoring and control in power plant auxiliary systems
- Control of cooling water circuits in industrial machinery where manual operation is impractical
- Valve operation in remote or hazardous zones where manual access is limited
Buyers It Suits
- Process control engineers specifying automated valves for water and heating systems
- EPC contractors sourcing integrated valve and actuator packages for industrial projects
- Facility operators upgrading manual valves to electrically controlled systems
- Valve distributors offering complete actuated valve solutions in the medium-pressure range
- Plant maintenance teams needing low-maintenance, long-life valves for high-cycle applications
How It Is Built
- Double eccentric disc design reduces contact with the seat during operation
- Resilient seat provides tight shut-off and low leakage under low pressure
- Flanged end connection for secure mounting to pipe flanges
- Electric actuator for automated quarter-turn operation
- Suitable for on-off and throttling duty in low- to medium-pressure lines
- Part of a product programme covering DN10 to DN2600 and 0.05 to 4.0 MPa
Material Selection
- Body, disc, stem, and seat materials are confirmed per order based on the medium and temperature
- Resilient seat material is selected from variants offered in the DE9D 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 double eccentric alignment
- Resilient seat fitted and tested for proper seating and sealing
- Electric actuator mounted and calibrated to the valve stem
- Fully assembled valve tested for operation, torque, and sealing before packing
- Marked, wrapped, and crated for shipment from Tianjin
How It Is Checked
- Dimensional checks on flange bolt pattern and face-to-face length before assembly
- Seat tightness and shell integrity tested on the assembled valve
- Actuator operation and full quarter-turn travel verified on every unit
- 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

What Can Be Changed
- Seat and disc material selected for the medium and temperature on the buyer's line
- Flange standard and drilling matched to the buyer's pipe system
- Electric actuator configured for voltage, signal type, and control mode
- Private label marking and packaging available on OEM orders
- Mixed-diameter and mixed-model orders combined in one container for export
How It Compares With the Alternatives
| Double eccentric flanged butterfly valve with manual lever | The manual version requires operator intervention; the electric actuator enables remote or automated control |
|---|---|
| Standard concentric flanged butterfly valve | The concentric design has higher seat wear and higher torque; the double eccentric reduces contact and wear |
| Gate valve with electric actuator | The gate valve has a full bore but is heavier, longer, and requires more space; the butterfly is compact and lighter |
| Ball valve with electric actuator | The ball valve offers tighter sealing at higher pressure but costs more and is not suitable for throttling |
Installing and Operating This Valve
- Confirm flange standard, bolt pattern, and actuator control signals before ordering
- Ensure the actuator power supply matches the site electrical system
- Mount the valve with flanges aligned and bolts tightened evenly in a cross pattern
- Test actuator operation and valve travel after installation
- Do not operate the valve continuously in a partially open position without throttling duty
- Perform periodic checks on actuator function and seal integrity

DE9D002 Double Eccentric Flange Butterfly Valve Resilient Seat and Electric Actuator FAQ
What size and pressure rating is DE9D002?
The nominal diameter and pressure rating are confirmed on request based on your line data, as the same model is available in multiple variants across the DN10 to DN2600 range and 0.05 to 4.0 MPa pressure range.
Can this valve be used for throttling?
Yes, the double eccentric design allows for throttling duty in low- to medium-pressure lines, but it is primarily intended for on-off service with minimal wear.
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 during quotation and issue material certificates with the order on request.
What type of electric actuator is fitted?
The actuator is configured for voltage, signal input, and control mode based on your system requirements. Details are confirmed during the quotation process.
Do you supply the larger diameters in the same series?
Yes. The DE9D flanged butterfly valve 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.
