Shanghai Zhibang Valve Manufacture Co., Ltd., established in 2016 and headquartered in Shanghai, China, is a dedicated manufacturer specializing in high-quality valve solutions. With an annual export value of US$1 Million to US$1.5 Million, we have built a strong reputation in global markets including North America, Europe, Southeast Asia, and the Middle East. Our Automatic DIN 3202 Electric Butterfly Valve for HVAC Systems is designed to deliver precise modulating control with a 0-90° rotation, ensuring optimal energy efficiency and reliable performance in heating, ventilation, and air conditioning applications. This valve combines robust engineering with advanced electric actuation to meet the demanding requirements of modern HVAC systems.
Our butterfly valve is engineered to provide seamless integration into HVAC networks, offering modulating control that allows for fine-tuned flow regulation. The DIN 3202 standard ensures compatibility with international piping systems, while the electric actuator provides smooth, accurate positioning from fully closed (0°) to fully open (90°). This product is ideal for applications requiring precise temperature and pressure management, such as air handling units, chillers, and cooling towers.
Key Features & Technical Specifications
- Modulating Control: The electric actuator supports 0-90° rotation with feedback signals (e.g., 4-20mA or 0-10V) for precise flow adjustment, enhancing system efficiency.
- DIN 3202 Compliance: Manufactured according to DIN 3202 face-to-face dimensions, ensuring easy installation and interchangeability in European-standard piping systems.
- Durable Construction: Available with a ductile iron or cast iron body, stainless steel or aluminum bronze disc, and customizable seat materials (EPDM, NBR, PTFE) to suit various media and temperatures.
- High Torque Actuator: The electric actuator provides reliable torque output, suitable for valves up to DN300, with IP67 protection for outdoor or harsh environments.
- Low Leakage Rate: Designed to meet Class A or Class B leakage standards (per ISO 5208), ensuring minimal fluid loss and energy waste.
- Easy Maintenance: The wafer or lug design allows for quick disassembly without disturbing the pipeline, reducing downtime.
