Note: These specifications are based on TWT Valve’s published eccentric butterfly valve product information. DN3600-specific pressure ratings, face-to-face dimensions, actuator torque, material combinations, and testing requirements must be confirmed before ordering.

Double-Eccentric Design and Operating Principle

A double-eccentric butterfly valve uses an offset arrangement between the disc, shaft, and sealing geometry. This design reduces continuous contact between the disc seal and seat during much of the opening and closing movement compared with a conventional concentric design.

When the actuator turns the shaft, the disc rotates to regulate or interrupt flow through the pipeline. In the closed position, the sealing components engage to provide the specified shut-off performance.

For a DN3600 valve, the final design must account for disc loads, differential pressure, shaft strength, sealing requirements, and the operating torque needed under actual service conditions.

An electric actuator can be selected to operate the valve through an electrical control system. Depending on the project requirements, the actuator package may include local controls, position indication, limit switches, and remote-control interfaces. The availability of these features should be confirmed for the selected actuator.

Electric Actuator Configuration for Large-Diameter Pipelines

For applications requiring automated operation, the DN3600 eccentric butterfly valve can be evaluated with an electric actuator configuration. Motorized operation can support centralized control in water transmission networks, pumping stations, and industrial pipeline installations.

Actuator selection should consider:

• Required operating torque under maximum differential pressure.
• Opening and closing time.
• Power supply and control signal requirements.
• Required protection rating and installation environment.
• Local operation, remote operation, and position feedback requirements.
• Operating frequency and emergency operating procedures.

Because DN3600 is an exceptionally large nominal diameter, the actuator should be selected using verified valve torque data rather than nominal diameter alone. Confirm the complete actuator and gearbox arrangement with the manufacturer before finalizing the purchase specification.

For other valve configurations, see TWT Valve’s butterfly valve product range to compare available structures and operating options.

Materials and Sealing Options

Material selection directly affects valve durability, sealing performance, and compatibility with the conveyed medium.

Component	Reference Material or Option	Selection Consideration
جسم الصمام	الدكتايل الحديد, ASTM A536 / GGG40	Pressure rating, pipeline loads, and corrosion protection
القرص	الدكتايل الحديد; alternative materials subject to configuration	Strength, fluid compatibility, and operating conditions
الفتحة	الفولاذ المقاوم للصدأ	Required strength and corrosion resistance
حلقة ختم القرص	EPDM or NBR	درجة حرارة, fluid compatibility, and sealing requirements
خاتم ختم الجسم	EPDM or NBR	Compatibility with the medium and operating conditions
Protective Coating	To be specified	Water quality, external environment, and project requirements

Alternative disc and shaft materials may be considered for more demanding service conditions. For seawater or chemically aggressive media, the complete wetted material combination and protective coating should be reviewed rather than assuming that standard ductile iron construction is suitable.

Applications of DN3600 Eccentric Butterfly Valves

Large-diameter eccentric butterfly valves can be considered for projects where pipeline isolation, flow control, and integration with operating equipment are required.

Typical application areas include:

• Water Transmission: Large-diameter pipelines and municipal water distribution infrastructure.
• Pumping Stations: Pipeline isolation around pumps and associated equipment.
• Industrial Water Systems: Process-water transmission and utility networks.
• Water Treatment Plants: Compatible water-treatment and distribution pipelines.
• Infrastructure Projects: Large-scale water conveyance and related engineering systems.

The final valve specification should reflect the actual medium, operating pressure, flow conditions, installation arrangement, and applicable project standards.

Installation, تقتيش, and Maintenance

Before installation, verify the valve’s face-to-face dimensions, flange drilling, pressure rating, flow requirements, and actuator clearance. Large-diameter valves may require dedicated lifting equipment and engineered installation procedures.

The installation and commissioning plan should address the following:

• Confirm that the pipeline flanges and valve dimensions match the approved drawings.
• Inspect the sealing surfaces and internal components before installation.
• Verify the actuator’s power supply, control signals, and travel limits.
• Check the valve’s opening and closing operation before placing the pipeline into service.
• Complete the specified pressure and functional tests in accordance with the approved inspection plan.

During operation, monitor actuator performance, leakage, abnormal vibration, corrosion, and changes in opening or closing behavior. Maintenance intervals should follow the manufacturer’s recommendations and the operating conditions of the pipeline.

Quality Assurance and Technical Documentation

For large-diameter valve procurement, the technical submittal should identify the valve model, nominal diameter, pressure rating, design standard, material grades, flange dimensions, actuator specifications, and inspection requirements.

Depending on the project, documentation may include dimensional drawings, material certificates, pressure-test reports, inspection records, actuator data sheets, and installation and maintenance instructions.

Confirm which documents and tests are available for the specific DN3600 configuration before placing the order.
