As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-quality industrial valves for global markets. Our DIN 3202 Electric Butterfly Valve is engineered specifically for demanding applications in water treatment plants, where reliable flow regulation and corrosion resistance are paramount. This valve combines robust construction with precise electric actuation to deliver consistent performance, reduce maintenance costs, and enhance the operational efficiency of your treatment systems.
This valve is designed to meet the rigorous requirements of water and wastewater management. Its core value lies in providing a durable, automated solution for controlling fluid flow in various stages of treatment, from intake and filtration to chemical dosing and discharge. By integrating this valve into your plant, you can achieve better process control, minimize leakage risks, and ensure long-term system integrity.
Key Features and Technical Specifications:
- Corrosion-Resistant Construction: The valve body and disc are typically made from materials like stainless steel (304/316) or coated carbon steel, offering excellent resistance to corrosive elements commonly found in water treatment environments, such as chlorides, acids, and alkalis.
- Precision Electric Actuation: Equipped with a high-quality electric actuator, the valve enables accurate and remote flow regulation. The actuator can be configured for on/off control or proportional modulation, supporting integration with PLCs and SCADA systems for automated plant operation.
- DIN 3202 Standard Compliance: Manufactured according to DIN 3202 standards for flanged connections, ensuring compatibility with common piping systems in water treatment infrastructure and facilitating easy installation.
- Effective Flow Regulation: The butterfly disc design provides smooth, linear flow control with low torque requirements, suitable for managing large volumes of water, sludge, or treated effluent.
- Robust Sealing Performance: Available with various sealing ring options (e.g., EPDM for general water, PTFE for aggressive media) to ensure tight shut-off and prevent leakage, crucial for maintaining process efficiency and environmental compliance.
- Low Maintenance Design: Simple mechanical structure and sealed actuator components reduce the need for frequent servicing, lowering operational downtime and long-term costs.

Frequently Asked Questions (FAQ):
-
What is the primary advantage of an electric actuator over a manual one for this butterfly valve?
An electric actuator enables remote, automated control. It can be integrated with plant control systems for precise, timely flow adjustments without manual operator intervention, enhancing automation, safety, and operational efficiency. -
Can this valve handle other media besides water in treatment plants, such as sludge or chemical solutions?
Yes. The corrosion-resistant materials and seal options (like PTFE) allow it to handle a range of media including mild slurries, certain chemical solutions, and treated wastewater. Specific media compatibility should be confirmed based on concentration and temperature. -
Is the valve suitable for both on/off and throttling (flow regulation) applications?
Yes. Depending on the electric actuator selected, it can perform simple on/off functions or provide proportional modulation for precise flow regulation throughout its opening range. -
How does the DIN 3202 standard benefit installation?
DIN 3202 defines flanged connection dimensions. This standardization ensures the valve matches commonly used flange sizes in many international piping systems, simplifying installation and reducing compatibility issues. -
What are the typical available sizes, and can custom sizes be provided?
Standard sizes typically range from DN50 to DN600. We can manufacture custom sizes outside this range upon request, subject to engineering review. -
What electrical specifications are available for the actuator?
Common voltage options include 24VDC, 110VAC, and 220VAC. Other voltages, control signals (e.g., 4-20mA), and protection features (like IP ratings) can be specified based on your plant's electrical standards. -
What maintenance is required for this electric butterfly valve?
Maintenance is generally minimal. Periodic checks of the actuator's electrical connections and lubrication of the stem/bearing (if accessible) may be recommended. The robust design aims to reduce frequent servicing needs. -
Does the valve come with any warranties or after-sales support?
As a manufacturer, we provide standard product warranties. Detailed warranty terms and after-sales technical support can be discussed upon inquiry, ensuring you have support for installation and operation.
