DIN Standard Ball Valve With 90° Rotation and 100,000 Cycle DurabilityNegotiableMOQ: 20 Units
Shanghai Zhibang Valve Manufacture Co., Ltd (established in 2016) proudly presents the CB/T4480 Bronze Electric Ball Valve DN80 2.0MPa with Modulating Actuator – a high-performance solution designed for precise flow control in demanding industrial applications. As a manufacturer with an annual export value of US$1–1.5 million and serving markets across North America, South America, Europe, Asia, and Africa, we combine advanced engineering with strict quality management to deliver reliable valve systems. This bronze ball valve integrates a modulating electric actuator for accurate modulating control, making it ideal for automation systems requiring proportional regulation.
The valve body is crafted from high-grade bronze, offering excellent corrosion resistance against seawater, steam, and many chemical media. The DN80 (3-inch) full-bore design ensures minimal pressure drop and high flow capacity, while the 2.0MPa (PN20) pressure rating handles medium-pressure applications with ease. The modulating actuator accepts standard 4-20mA control signals, enabling smooth and precise positioning from 0° to 90° rotation. Below you will find the key technical specifications, product features, and practical benefits that make this valve a trusted choice for global buyers.

Product Features & Advantages
- Bronze Body Material: Excellent corrosion resistance to seawater, steam, mineral oils, and mild chemicals. Suitable for marine, HVAC, and water treatment applications.
- Full Bore Design: DN80 full-bore minimizes flow resistance and pressure drop, allowing high flow rates with low torque requirements.
- Modulating Electric Actuator: Provides precise proportional control via 4-20mA input signal. The actuator features a brushless motor, manual override, and position feedback (4-20mA output) for closed-loop control.
- High Pressure Rating: 2.0MPa (PN20) ensures reliable operation in medium-pressure systems up to 20 bar. The valve body is hydrostatically tested at 3.0MPa as per industry standards.
- Flanged Connection: Standardized EN 1092-1 flanges provide easy installation and secure sealing with gaskets. Available in PN16 or PN20 drilling patterns.
- Durable Sealing Materials: PTFE or reinforced PTFE seat offers low friction, long cycle life, and excellent chemical resistance. Optional high-temperature seals available for extended temperature ranges.
- Low Maintenance: Self-lubricating stem bearings and a blow-out-proof stem design reduce maintenance intervals. The actuator is sealed against dust and moisture (IP65).
- Versatile Control Options: Compatible with most PLCs, DCS, or building automation systems. The actuator can also be configured for on/off service with 3-point floating control.
- Customizable Features: Voltage, feedback signal, actuator speed, and auxiliary switches can be tailored to specific project requirements upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between a modulating actuator and an on/off actuator?
A: A modulating actuator (like this one) receives a continuous analog signal (e.g., 4-20mA) and can position the valve at any angle between 0° and 90°, enabling precise flow regulation. An on/off actuator only opens or closes the valve fully. Modulating actuators are used in processes requiring proportional control, such as temperature or pressure regulation. -
Q: Can this valve be used for seawater applications?
A: Yes, the bronze body offers excellent resistance to seawater corrosion. However, you should consider the compatibility of the actuator housing (IP65 standard) with saltwater environments. We recommend an IP67 protection for outdoor marine installations. Additional protective coatings are available upon request. -
Q: What control signals are supported?
A: The standard actuator accepts a 4-20mA DC control signal. Optionally, we can provide 0-10V DC, 2-10V, or PWM input. For feedback output, 4-20mA is standard. Please specify your requirements when ordering. -
Q: Is the actuator manual override included?
A: Yes, the modulating actuator is equipped with a manual override handwheel or hex key for emergency manual operation. This allows you to adjust the valve position even without power. -
Q: What is the maximum working pressure at high temperature?
A: At 120°C (248°F), the pressure rating may be reduced due to seat material limitations. For standard PTFE seats, the maximum working pressure at 120°C is approximately 1.6 MPa. If you need full 2.0MPa at elevated temperatures, we recommend our reinforced PTFE or PEEK seat options. Please consult our technical team for specific derating curves. -
Q: Do you provide certificates of material and pressure test?
A: Absolutely. We can issue Material Certificate (EN 10204 3.1) and Hydrostatic/Pneumatic Test Report upon request. Our ISO9001 quality system ensures traceability. -
Q: What is the lead time and shipping options?
A: For standard configurations, the lead time is 15-25 working days. Expedited production is available for urgent orders. We ship from Shanghai, Guangzhou, Hong Kong, or Beijing via sea, air, or express courier (DHL, FedEx, UPS). -
Q: Can the valve be used with potable water?
A: Yes, bronze is a common material for potable water systems. However, you should verify that the internal coatings (if any) and the actuator materials are suitable for drinking water contact. Our standard product does not use leaded bronze, but we can provide NSF/ANSI 61 certification upon request for an additional cost.
