As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable and efficient flow control solutions for global industrial markets. Our DN50 to DN250 Electric Ball Valve with Remote Control is engineered for precision, durability, and seamless integration into automated systems. Designed in strict compliance with the DIN 3357 standard, this valve represents our commitment to delivering high-quality industrial components that meet international specifications and performance expectations. With an annual export value reflecting our global reach across North America, South America, Europe, Asia, and beyond, we understand the diverse requirements of different markets and applications.
This electric ball valve is a cornerstone for modern process automation, offering superior shut-off capability and reliable remote operation. It eliminates the need for manual intervention in hard-to-reach or hazardous locations, enhancing both operational safety and efficiency. The integration of a robust electric actuator allows for precise control over fluid flow, making it an ideal choice for applications demanding repeatable and accurate performance. Our manufacturing processes, backed by ISO9001 certification, ensure consistent quality and reliability in every unit we produce.
Core Product Features & Technical Advantages:
- Robust Construction & Standard Compliance: The valve body and components are manufactured to meet the dimensional, pressure, and testing requirements of DIN 3357, ensuring interchangeability and reliable performance in demanding industrial environments.
- Versatile Remote Control: The electric actuator enables operation from a central control room, SCADA system, or via handheld remote. Options for on/off control or proportional modulating control (4-20mA, 0-10V) are available to suit various process needs.
- Excellent Sealing Performance: Utilizes advanced seat materials like PTFE or reinforced PTFE, providing bubble-tight shut-off, low operating torque, and high resistance to a wide range of media including water, oil, gas, and mild chemicals.
- Wide Size and Pressure Range: Available from DN50 (2") to DN250 (10"), catering to different pipeline dimensions. Standard pressure ratings include PN16 and PN25, with higher ratings available upon request.
- Durable Actuator Design: The electric actuator features thermal overload protection, manual override capability, and position indicator. Enclosure protection ratings up to IP68 are optional for harsh or outdoor installations.
- Easy Installation & Maintenance: Standard flanged connections (e.g., DIN EN 1092-1) simplify integration into existing pipelines. The modular design allows for easy actuator replacement or maintenance without removing the valve body from the line.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of choosing an electric actuator over a pneumatic one for this ball valve?
A: Electric actuators provide a self-contained solution requiring only a power and control signal cable, eliminating the need for compressed air lines, dryers, and filters. This simplifies installation, reduces auxiliary equipment costs, and is often preferred for remote sites or where clean, dry air is not readily available. -
Q: Can this valve be used for throttling or flow control applications, or is it only for on/off service?
A: While the standard version is designed for reliable on/off service, we offer modulating electric actuators as an option. These actuators can precisely position the ball to regulate flow based on a continuous control signal (like 4-20mA), making the valve suitable for proportional control applications. -
Q: How does compliance with DIN 3357 benefit me as a buyer?
A: DIN 3357 is a widely recognized European standard for flanged ball valves. Compliance guarantees specific dimensions, pressure-temperature ratings, material grades, and testing procedures. This ensures valve quality, interchangeability with other compliant components, and simplifies procurement for projects with European standards or global specifications. -
Q: What is the typical lead time for an order of these valves?
A: For standard configurations in popular sizes (DN50-DN150), we typically maintain stock or can deliver within 15-30 days. For larger sizes (DN200-DN250), special materials, or specific actuator options, the lead time may extend to 30-45 days. We provide accurate timelines upon receipt of your detailed specifications. -
Q: What after-sales support and warranty do you provide?
A: We offer a standard warranty period of 12 months from the date of shipment against manufacturing defects. Our technical team provides support for installation guidance, troubleshooting, and spare parts identification. Comprehensive operation and maintenance manuals are included with each shipment. -
Q: Are customization options available for special applications?
A> Yes. We can customize various aspects including special body/trim materials for corrosive or high-temperature services, extended stem lengths for insulated lines, different flange standards (ANSI, JIS), fire-safe design per API 607/API 6FA, and actuators with specific protection classes or explosion-proof certifications. Please consult with our engineering team for your specific requirements. -
Q: From which ports can you ship, and what are the common Incoterms you work with?
A: We primarily ship from major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing. We are experienced in handling exports under common Incoterms such as FOB, CIF, and CFR to our main markets worldwide, ensuring smooth logistics for our customers.
