As a professional valve manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance Electric Butterfly Valve series. Engineered to meet the rigorous DIN 3202 F4 standard, this valve is the result of our commitment to reliability, precision, and ease of maintenance. We understand that in industries from water treatment to chemical processing, downtime is not an option. That's why every valve undergoes factory calibration and testing before shipment, ensuring it performs flawlessly from the moment it's installed. With our extensive global reach, serving markets from North America to Oceania, we have tailored this product to meet diverse international requirements, offering a robust solution for automated flow control.
Our Reliable Electric Butterfly Valve is designed for durability and precise operation. The core of its reliability lies in the factory calibration of the electric actuator with the valve body. This pre-set integration eliminates on-site alignment errors, guarantees optimal sealing, and ensures accurate positioning for both on/off and modulating control duties. The valve construction adheres strictly to the DIN 3202 F4 standard for face-to-face dimensions and flange connections, ensuring direct interchangeability and easy installation in existing piping systems designed to European norms.
Key Features & Technical Advantages:
- Superior Sealing Performance: Utilizing high-quality seat materials like EPDM for water, NBR for oils, or PTFE for corrosive media, the valve ensures bubble-tight shut-off, minimizing leakage and product loss.
- Robust Actuator Design: The electric actuator features a thermally protected motor, mechanical position indicators, and manual override capability. It is designed for high cycle life and reliable operation in demanding environments.
- Flexible Control Integration: Compatible with standard control signals, the valve can be easily integrated into PLC, DCS, or building management systems for automated process control.
- Corrosion Resistance: Available in various body and disc materials, including epoxy-coated ductile iron and stainless steel (SS304/SS316), to suit different fluid compatibilities and environmental conditions.
- Low Maintenance Design: The streamlined disc design minimizes pressure drop and turbulence. The self-lubricating bearings and easily accessible actuator housing simplify routine maintenance.

Frequently Asked Questions (FAQ):
-
What does "Factory Calibrated" mean for this valve?
It means the electric actuator is precisely matched and set to the specific valve body at our factory. The torque settings, limit switches, and positioning are pre-configured, ensuring optimal performance and eliminating installation errors. -
Is this valve compatible with my existing DIN standard piping?
Yes. The valve is manufactured to DIN 3202 F4 for face-to-face dimensions and typically uses flanges per DIN 2501. This ensures direct replacement and compatibility with systems built to European standards. -
What spare parts are typically available?
We maintain stock for critical wear parts including seat seals (EPDM, NBR, etc.), shaft seals, bearings, and gasket kits. Actuator components like gears and limit switches are also available. -
Can the valve be used for throttling or flow control?
Yes. When paired with a modulating electric actuator (accepting 4-20mA or 0-10V control signals), this butterfly valve can provide precise proportional flow control, not just on/off service. -
What is the lead time for orders?
Standard sizes and materials often have shorter lead times. For specific delivery schedules, please contact our sales team with your quantity and specification requirements. -
How do I select the right seat material?
Selection depends on the fluid media, temperature, and pressure. EPDM is common for water, NBR for oils, and PTFE or FKM for aggressive chemicals. Our technical team can provide guidance based on your application details. -
Does the actuator have a manual override?
Yes. A manual handwheel or crank is provided as a standard feature on the electric actuator, allowing for manual operation in case of power failure or for maintenance purposes. -
What after-sales support do you offer?
We provide technical documentation, installation manuals, and support for troubleshooting. For complex issues, our engineering team is available for consultation.
