As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance Stainless Steel Marine Electric Ball Valve. Engineered for demanding marine and offshore applications, this valve combines the corrosion resistance of stainless steel with precise 4-20mA control signal compatibility, offering reliable and automated flow control solutions for shipbuilding, ballast systems, and offshore platforms. Our commitment to quality, backed by years of experience since 2016 and an annual export value reflecting global trust, ensures you receive a durable, low-maintenance valve designed for long-term operation in harsh saline environments.
This electric actuated ball valve is a cornerstone for modern fluid control systems where automation, reliability, and safety are paramount. Its flanged connection ensures easy integration into existing piping networks, while the 4-20mA signal interface allows seamless integration with PLCs, DCS, and other industrial control systems for precise remote operation and monitoring.
Core Product Features & Technical Advantages:
- Superior Corrosion Resistance: Constructed from high-grade stainless steel (typically 316 or 304), the valve body, ball, and stem offer exceptional resistance to saltwater, chemicals, and atmospheric corrosion, making it ideal for marine applications.
- Precise Automated Control: The integrated electric actuator responds accurately to the standard 4-20mA control signal, enabling proportional modulation or on/off control. This allows for precise flow rate management and seamless integration into automated ship systems.
- Robust & Leak-proof Design: The flanged connection, coupled with high-quality sealing materials like PTFE, ensures a tight, leak-proof seal even under high pressure and vibration conditions common in marine environments.
- Low Maintenance & High Reliability: The simple yet robust design of the ball valve mechanism, combined with a sealed actuator, minimizes the need for frequent maintenance, reducing lifecycle costs and downtime.
- Versatile Power Options: The electric actuator is available with multiple standard power supply voltages (e.g., 24VDC, 110VAC, 220VAC) to suit different shipboard power systems.
- Safety & Fail-Safe Options: Models with fail-safe features (spring return) are available, ensuring the valve moves to a predefined safe position (open or closed) in case of power loss, critical for safety systems.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater applications?
A: Yes, absolutely. The primary construction material is AISI 316 stainless steel, which offers excellent resistance to pitting and crevice corrosion caused by chlorides in seawater, making it a standard choice for marine environments. -
Q: How does the 4-20mA control work with this electric ball valve?
A: The valve's electric actuator receives a 4-20mA signal from your control system (PLC/DCS). Typically, 4mA corresponds to the valve being fully closed, 20mA to fully open, and any value in between for proportional positioning, allowing precise flow control. -
Q: Can I get this valve with different flange standards?
A: Certainly. We commonly provide flanges per ANSI (US standard), DIN (European standard), and JIS (Japanese standard). Please specify your required pressure class (e.g., ANSI 150, PN16) and drilling standard when inquiring. -
Q: What happens if there is a power failure on the ship?
A: For critical applications, we offer actuators with a fail-safe (spring return) mechanism. Upon power loss, the internal springs automatically drive the valve to a pre-set safe position (fully open or closed) as required by your system design. -
Q: What is the lead time for an order?
A: Lead times vary based on order quantity, size, and specific configuration. Standard models may have shorter lead times. We provide estimated lead times upon receipt of your detailed inquiry or purchase order. -
Q: Do you provide customization for specific voltage or signal requirements?
A: Yes, customization is a key strength. We can configure the actuator for various AC/DC voltages and can also provide different feedback signals (e.g., potentiometer, switch contacts) alongside the standard 4-20mA. -
Q: What kind of warranty do you offer?
A: Our valves come with a standard warranty against manufacturing defects. The specific warranty period and terms are provided with the commercial proforma invoice and can be discussed based on the application. -
Q: Can you supply the necessary documentation for marine classification societies?
A> While our standard certification is ISO9001, documentation for specific marine classification society approvals (like ABS, DNV, LR, etc.) can be arranged upon request. Please discuss your specific certification requirements with our sales team.
