| Operating Temperature | -20°C to +150°C (depending on seals) |
Key Features and Customer Benefits
- Superior Corrosion Resistance: The bronze body and trim provide excellent resistance to seawater and saline atmospheres, ensuring long service life in marine environments. This reduces maintenance costs and replacement frequency.
- Reliable Limit Switch Feedback: Built-in limit switches (SPDT/DPDT) give precise open/close position indication. The dry contact signal can be integrated directly into PLC, SCADA, or remote monitoring systems, enabling real-time valve status tracking.
- Robust Electric Actuator: The actuator is designed for high torque output and continuous duty. It features manual override for emergency operation, thermal overload protection, and a durable gear train. Available in multiple voltage options to suit your facility's power supply.
- Compact and Lightweight: Compared to pneumatic or hydraulic actuators, the electric actuator is lighter and more compact, saving installation space and simplifying mounting on pipelines in tight shipboard areas.
- Easy Installation and Maintenance: The valve can be supplied with flanged or threaded connections per your requirements. The actuator housing is sealed (IP67) against water ingress, and the wiring terminal is clearly marked for quick field wiring. Routine maintenance is minimal.
- Customizable Options: We offer a range of optional features such as explosion-proof actuator (Exd), high-temperature seals, stainless steel trim, and additional positioners (4-20mA feedback). Please consult our sales team for your specific needs.
Application Scenarios
This marine electric actuated bronze ball valve is widely used in:
- Seawater cooling systems on ships and offshore platforms
- Bilge and ballast water management
- Fuel oil transfer and bunkering systems
- Freshwater and fire-fighting systems
- Coastal desalination plants and port facilities
The combination of bronze material and electric actuation with limit switch feedback makes this valve a reliable solution for automated flow control in harsh marine environments. It helps operators reduce manual intervention, improve safety, and gain operational efficiency.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this valve?
A: For standard sizes and configurations, lead time is 15–25 working days. Custom orders may take 30–40 days. Please confirm with our sales team. -
Q: Can the actuator be used with 24V DC power?
A: Yes, DC 24V is available as an option. Other voltages (AC 110V, 220V, 380V) are also standard. Please specify your requirement when ordering. -
Q: Does the limit switch provide a visual indicator?
A: The standard limit switch is a dry contact signal. For visual indication, we can add a mechanical position indicator on the actuator top. Additional options include a local LED indicator. -
Q: Is the valve suitable for subsea applications?
A: The standard IP67 protection allows temporary submersion (1 meter for 30 minutes). For continuous subsea use, we recommend an IP68-rated actuator. Please contact us for custom solutions. -
Q: What certifications does the product have?
A: Our factory is ISO9001 certified. The product itself can be manufactured to meet various standards (e.g., API, ANSI, JIS) upon request. Please inquire about specific certification requirements. -
Q: Can the valve be operated manually if the power fails?
A: Yes, the electric actuator is equipped with a manual override handwheel, allowing you to operate the valve manually during power outages. -
Q: What is the maximum operating pressure?
A: Standard pressure rating is PN16 (16 bar). Optional PN25 (25 bar) or Class 150 (approx. 20 bar) is available. Higher pressure ratings can be customized. -
Q: Do you provide samples for testing?
A: Yes, we offer sample orders. Please contact us to discuss sample cost and shipping arrangements.
