Butterfly Valve


Industrial Butterfly Valves for Reliable Flow Control


SDF butterfly valves are designed for shutoff, isolation, and flow control in industrial pipeline systems. They are suitable where compact structure and efficient operation are important.

Founded in 1966, Shanghai Power Plant Valve Factory Co., Ltd. supports demanding sectors such as power generation, petrochemical, oil & gas, chemical processing, metallurgy, and marine applications. We can configure these valves for manual or automated operation based on pipeline layout, media conditions, and project control requirements.

Compared with many general-purpose flow control valves, industrial butterfly valves offer quarter-turn operation and compact installation. They are also practical for large-diameter pipeline applications when the model is selected correctly.

Contact SDF for butterfly valve selection, technical review, and project support based on your operating conditions.

 


Butterfly Valve Types Available from SDF


SDF supplies several butterfly valve configurations for different installation styles, media conditions, actuation needs, and maintenance requirements. The right choice depends on pipeline standards, pressure, temperature, shutoff expectations, chemical compatibility, and control requirements.

Butterfly Valve Type Typical Use Key Selection Notes
Wafer butterfly valves Compact installation between pipeline flanges Suitable for space-saving isolation and flow control where the pipeline supports wafer mounting
Lug butterfly valves Industrial pipeline isolation with bolted installation flexibility Often considered when maintenance access and flange bolting arrangement are important
PTFE lined butterfly valves Corrosive or chemically aggressive media Material compatibility should be reviewed for chemical, petrochemical, and pharmaceutical service
Pneumatic butterfly valves Automated open-close or process operation Selected when compressed air control, remote operation, or plant automation is required
Electric and motorized butterfly valves Remote control and electrically actuated systems Useful for electric actuation, signal integration, or centralized operation
Gear operated butterfly valves Manual operation with torque assistance Commonly used when larger sizes or operating conditions require easier local operation


Wafer Butterfly Valves

Wafer butterfly valves are commonly selected for compact installation between pipeline flanges. Their space-saving structure supports reliable shutoff or general flow control without a long valve body.

A wafer configuration should be selected according to flange standard, pressure rating, media, temperature, sealing requirements, and installation orientation. SDF can review project conditions and confirm whether this type suits the intended pipeline system.


Lug Butterfly Valves

Lug butterfly valves are used where flange bolting arrangement and installation flexibility are important. This configuration can support industrial pipeline isolation and maintenance-oriented layouts, depending on service conditions.

When specifying a lug type, buyers should consider pipe size, flange compatibility, pressure class, body material, seat or lining material, and actuation method. SDF supports selection based on engineering data and project standards.


PTFE Lined Butterfly Valves

PTFE lined butterfly valves are often considered for corrosive or chemically aggressive media. In these applications, lining compatibility is a major selection factor.

For chemical processing, petrochemical, pharmaceutical, and related fluid handling applications, lined designs can help address corrosion resistance needs. They must be matched correctly to the process medium.

Because chemical service conditions vary widely, SDF recommends confirming media concentration, operating temperature, pressure, cleaning procedures, and compatibility requirements before final specification.


Pneumatic and Electric Butterfly Valves

Pneumatic and electric butterfly valves are used when remote operation, automated switching, or plant control integration is required. SDF supports pneumatic, electric, motorized, gear operated, and manual actuation based on project needs.

For automated valves, actuator selection should consider operating frequency, available power source, control signal, opening and closing time, installation environment, and fail-safe requirements. Sharing these details helps our team recommend a more suitable configuration.

Butterfly Valve Materials, Actuation and Technical Options


Butterfly valve materials and actuation choices should match the actual media, pressure, temperature, pipeline size, corrosion risk, control requirement, and installation environment. SDF manufactures a wide industrial valve portfolio covering DN10 to DN4000, 1.6 MPa to 80.0 MPa, Class 150 to Class 4500, and -196°C to 1100°C.

Final butterfly valve specifications must be confirmed by model, design, and application. The following table summarizes common selection directions for inquiry preparation.

Selection Item Available or Common Direction Buyer Consideration
Body material Stainless steel, carbon steel, cast steel, alloy steel, ductile iron where applicable Match material to pressure, temperature, corrosion exposure, and plant standards
Seat or lining PTFE lined configurations where applicable Review chemical compatibility, media concentration, temperature, and shutoff expectations
Connection style Wafer and lug butterfly valve configurations Confirm flange standard, bolting arrangement, installation space, and maintenance needs
Actuation Manual, gear operated, pneumatic, electric, motorized Select according to operating frequency, automation level, power source, and control system
Pressure and size SDF valve portfolio covers broad industrial ranges; final data depends on model Provide design pressure, nominal size, flange rating, and project standard
Temperature SDF valve portfolio covers cryogenic to ultra-high-temperature applications; final suitability depends on model Confirm normal, minimum, and maximum operating temperature


Material Options for Industrial Butterfly Valves

Material selection is an important step in industrial butterfly valve specification. Stainless steel may be considered where corrosion resistance is important.

Carbon steel, cast steel, alloy steel, or ductile iron may be selected depending on pressure, temperature, media type, and project standards. For corrosive service, PTFE lined options may be reviewed when media compatibility is a primary concern.

SDF recommends providing complete process data. This helps our team evaluate body, disc, stem, seat, and lining requirements together.


Manual, Gear Operated, Pneumatic and Electric Actuation

Manual butterfly valves are typically suitable for local operation where frequent remote control is not required. Gear operated types can provide easier local operation, especially when size or torque makes direct manual operation less practical.

Pneumatic and electric butterfly valves are better suited to automated systems, remote operation, and process control integration. To support actuator selection, buyers should share the control signal, function, power source, fail-safe preference, cycle frequency, and installation environment.

SDF supports industrial buyers in evaluating wafer, lug, gear operated, pneumatic, and electric options for project-specific pipeline systems. Final selection should be based on engineering data, project standards, and service conditions.

 


How to Select the Right Butterfly Valve


Butterfly valve selection should begin with clear operating data. A suitable valve is not determined by size alone.

It also depends on pressure rating, temperature range, media characteristics, shutoff requirements, flange standard, actuation method, and installation environment. When comparing wafer vs lug, PTFE lined vs metal body, or manual vs automated operation, consider how the valve will be installed, operated, and maintained.

SDF can review drawings, datasheets, or operating conditions to support industrial butterfly valve specification.

Selection Question Why It Matters Information to Provide
What is the pipeline size? Determines valve dimension, connection, and operating torque direction DN or NPS size, pipe schedule if relevant
What are the pressure and temperature conditions? Affects body material, seat design, sealing, and model suitability Design pressure, operating pressure, minimum and maximum temperature
What media will pass through the valve? Impacts corrosion resistance and lining or seat compatibility Fluid name, concentration, solids content, viscosity, corrosiveness
What connection standard is required? Ensures proper installation between pipeline flanges Flange standard, pressure class, wafer or lug preference
How will the valve be operated? Determines manual, gear, pneumatic, electric, or motorized actuation Local or remote operation, control signal, cycle frequency, power source
What shutoff or control function is expected? Helps define valve type and actuator configuration On-off isolation, flow control, automation requirement, leakage expectation
  • Choose wafer butterfly valves when compact flange-to-flange installation is preferred and suitable for the system design.
  • Choose lug butterfly valves when bolting arrangement, isolation, or maintenance access requires this configuration.
  • Consider PTFE lined butterfly valves when corrosion resistance and chemical compatibility are key concerns.
