Electric Spherical Butterfly Valve

Introduction

The Electric Spherical Butterfly Valve is a highly efficient solution designed for precise flow control in a wide range of industrial applications. Combining the traditional advantages of a butterfly valve with the precision of electric actuation, this valve is ideal for automated systems, providing reliable, consistent, and precise flow regulation. Its spherical disc design ensures minimal pressure drop, and smooth flow, which makes it ideal for handling both liquid and gas flows in critical applications such as chemical processing, water treatment, HVAC systems, and food and beverage industries.

With a robust design, electric actuation, and easy integration into automated control systems, the Electric Spherical Butterfly Valve offers long-lasting performance and energy-efficient operation under even the most demanding conditions.

Product Advantages

1. Electric Actuation for Precision Control

• Automated operation ensures remote control with the integration of PLC and SCADA systems, allowing for precise, real-time flow adjustments.

• Offers on/off and modulating control for flexible application in both low and high-demand systems.

• Equipped with limit switches and feedback sensors to monitor valve status for continuous performance tracking.

2. Spherical Disc Design for Efficient Flow

• The spherical disc enhances the smoothness of flow, reducing turbulence and achieving minimal pressure loss.

• The spherical shape also contributes to better sealing, ensuring a leak-proof operation and long-term durability.

• This design is ideal for high-velocity fluid applications where high flow rates are required.

3. Durable and Reliable Construction

• The valve body is typically made from corrosion-resistant stainless steel (SS304 or SS316), ensuring long-lasting durability even in harsh environments.

• High-performance seals made of PTFE or FDA-approved elastomers provide excellent chemical resistance and reliable leak-proof operation.

• The valve is designed for use in both high-temperature and high-pressure systems, making it suitable for a variety of industrial environments.

4. Ease of Maintenance

• The simple design and quick-release mechanism allow for easy disassembly, inspection, and replacement of parts.

• Minimal wear and tear due to the smooth operation of the spherical disc ensures the valve requires less frequent maintenance compared to traditional valves.

• Modular design makes it easy to replace components such as the actuator, seals, and valve body without removing the entire valve from the pipeline.

5. Energy Efficiency

• The electric actuator allows for precise control of valve position, reducing energy consumption compared to pneumatic or manual valve systems.

• Low-pressure drop through the spherical disc results in energy savings during operation, especially in systems with high flow rates.

Technical Specifications

Below are the technical parameters and key specifications for the Electric Spherical Butterfly Valve:

Safety Operating Procedures

1. Pre-Operation Checks

• Inspect valve components for signs of damage, wear, or corrosion.

• Ensure electrical wiring is properly connected and that the actuator power supply is functioning correctly.

• Verify that the valve body and actuator are properly aligned with the pipeline to avoid mechanical stress.

• Check seals and O-rings to ensure they are in good condition and securely in place.

2. Operational Safety

• Do not exceed the rated pressure or temperature limits as indicated in the product specifications.

• Ensure that the actuator power supply matches the valve's voltage rating to avoid electrical issues.

• Ensure that the manual override feature works in case of an emergency, and that the valve can be operated manually if required.

3. Shutdown and Maintenance

• Before performing any maintenance, ensure the power supply to the actuator is turned off and the system is depressurized.

• Always use personal protective equipment (PPE) when handling hazardous fluids or when working on high-pressure systems.

• Disassemble and clean the valve regularly to prevent clogging and ensure smooth operation. Use non-abrasive cleaning solutions to avoid damaging the seals and valve body.

Performance Testing

The Electric Spherical Butterfly Valve undergoes rigorous testing to ensure high performance, reliability, and durability:

1. Pressure and Leak Testing

• Seat Leak Test: Each valve is tested to ensure that the seat does not leak under the maximum rated pressure.

• Body Leak Test: The valve body is pressurized to ensure there are no leaks at the joints and seals.

• Hydraulic Pressure Test: The valve is subjected to a hydraulic test at 1.5 times its maximum rated pressure to confirm structural integrity.

2. Actuator Functionality Testing

• The actuator undergoes torque testing to ensure it can provide the necessary force to open and close the valve without failure.

• The actuator is also tested for electrical performance, ensuring that the valve responds appropriately to control signals.

• The limit switches are tested to ensure the valve reaches the correct open or closed position.

3. Flow Performance Test

• The valve’s flow characteristics are measured to ensure it meets the required flow rates with minimal pressure drop.

• The valve’s ability to modulate flow is tested to ensure smooth operation and accurate flow control in various system conditions.

How to Use the Electric Spherical Butterfly Valve

1. Installation

• Ensure proper valve alignment with the pipeline to avoid stress and ensure proper sealing.

• Use the appropriate gaskets and sealing materials to ensure leak-free operation.

• Connect the actuator to the power supply and integrate it with the PLC or automation system for remote control.

2. Operation

• Use the control system to open or close the valve according to system requirements.

• Monitor the valve position indicator to confirm the valve’s status.

• Adjust the flow rate if the valve has modulating control capabilities to achieve the desired performance.

3. Maintenance

• Inspect the valve regularly for leaks or signs of wear.

• Replace seals and O-rings as necessary, especially if there are any signs of fluid leakage.

• Test the actuator periodically to ensure it functions correctly and that there is no malfunction in the electrical system.
