02

Connection Type & Size

Define nominal pipe size (typically DN40-DN1200 / 1.5"-48") and standard body connections: Wafer, Lugged, Flange (ANSI/DIN/JIS), or Groove.

03

Body, Disc & Seat Materials

Select body/disc materials (Ductile Iron, WCB, SS316, UPVC) and seat liners (EPDM, NBR, PTFE, or Metal-to-Metal) strictly compatible with your process medium.

04

Operating Temperature

Provide working temperature ranges (-20°C to +425°C+) to determine if standard elastomer seats, high-temp fluorine-lined, or metal hard-seated configurations are required.

05

Pipeline Working Pressure

Specify system pressure ratings (PN10-PN64 / Class 150-300) to verify valve body rating and calculate the exact breakaway torque for accurate actuator sizing.

06

Actuator Operating Voltage

Select power supply specifications for your site control panel: DC24V, AC24V, AC110V, AC220V, or heavy-duty 3-Phase AC380V.

07

Control Method & Signal

Choose operational modes: On/Off type, Intelligent Modulating (4-20mA/0-10V control signal), fail-safe backup, or digital fieldbus integration (Modbus/DCS).

Why Choose DELCO Electric Butterfly Valves?

Advanced Motorized Control

Driven by heavy-duty intelligent actuators, our quarter-turn butterfly series ensures rapid actuation and precise flow modulation. These units are built for immediate compatibility with modern industrial automation setups, including PLC and advanced fieldbus architectures.

Large-Diameter Sealing Integrity

Utilizing streamlined discs and resilient seating materials, these valves minimize pressure drop while providing bubble-tight isolation. They are specifically optimized to safely manage massive fluid volumes in large-scale municipal, HVAC, and chemical networks.

Optimized Power Efficiency

Relying on motor-driven gearboxes that mechanically lock in place upon reaching the desired angle, our valves consume zero standby energy. This self-locking mechanism not only slashes electricity costs but also prevents disc fluttering under high fluid velocities.

Comprehensive Pipeline Adaptability

We manufacture fluid control solutions for any challenge. Whether your project requires plastic or fluorine-lined bodies for corrosives, hard-seated trims for extreme heat, or sanitary finishes for hygiene—securely mounted via wafer, lugged, flange, or groove formats—DELCO has you covered.

Rigorous Factory Validation

Quality is non-negotiable. As a direct manufacturer, we subject every completed valve-actuator package to strict hydrostatic pressure tests, pneumatic seal checks, and electronic stroke calibrations to certify zero defects prior to global shipment.

Expert Engineering & Sizing

Selecting the correct actuator torque for a butterfly valve is critical. Our dedicated technical team supports distributors and contractors with precise breakaway torque calculations, complete 3D models, and wiring schematics to guarantee flawless field installation.

Frequently Asked Questions

Find expert answers to critical questions regarding actuator sizing, fail-safe operations, and DCS integration, or contact our engineering team directly for project-specific solutions.

What happens to the electric butterfly valve if there is a sudden power outage?+

Pipeline safety is our priority. All DELCO heavy-duty electric actuators come standard with a mechanical self-locking worm gear and a manual override handwheel. In the event of a power failure, the valve will firmly hold its last position against fluid pressure. Operators can simply engage the declutch mechanism and use the handwheel to manually open or close the valve safely. We also offer optional fail-safe battery backup systems for critical pipelines.

How do you ensure the electric actuator has enough torque, especially for large-diameter butterfly valves?+

Under-sizing the actuator is a common cause of automated valve failure. At DELCO, we never guess. Our engineering team calculates the exact breakaway torque based on your specific medium, pipeline working pressure (e.g., PN16, Class 300), and seat friction. We always apply a strict 20% to 30% torque safety margin when sizing the actuator to guarantee reliable, jam-free operation over thousands of cycles.

Can your motorized butterfly valves handle abrasive mining slurries or highly corrosive chemicals?+

Absolutely. We manufacture application-specific trims to combat severe media. For aggressive acids and alkalis, we supply premium fluorine-lined (PTFE/PFA) or plastic (UPVC) butterfly valves. For abrasive mineral slurries, ash handling, or high-temperature steam, our metal-to-metal hard-seated configurations deliver exceptional wear resistance and long service life.

Are your electric actuators compatible with our plant’s existing PLC or DCS control systems?+

Yes, DELCO automated valves are built for seamless integration. Beyond standard On/Off operation, we offer Intelligent Modulating actuators that accept industry-standard 4-20mA or 0-10V control signals for precise flow regulation. For advanced digital networking, we can configure your actuators with Modbus, Profibus, or CANopen communication protocols tailored to your exact DCS architecture.

Do you provide the technical documentation required for engineering project bids?+

As a direct manufacturer, DELCO fully supports distributors and EPC contractors. Upon request, our technical team will quickly provide comprehensive technical data sheets, torque calculation reports, detailed CAD/3D drawings, and wiring schematics to help you win project bids and ensure flawless field installation.
