As a dedicated manufacturer with a strong foothold in the global marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our specialized Marine Ball Valve for Ship HVAC Systems with Electric Actuator. Engineered to meet the rigorous demands of maritime environments, this valve is a cornerstone for reliable and efficient fluid control in heating, ventilation, and air conditioning systems onboard vessels. Our commitment, backed by ISO9001-certified processes since 2016 and an annual export value reflecting consistent quality, ensures that every valve delivers the performance, durability, and precise remote operability that shipbuilders and operators worldwide depend on.
This valve is designed to be the intelligent interface between your ship's automation system and its critical HVAC circuits. It transforms manual, labor-intensive valve operations into seamless, remote-controlled commands, enhancing both operational safety and efficiency. Below are the key features and technical specifications that define its superior performance:
- Robust Marine-Grade Construction: The valve body is precision-crafted from corrosion-resistant materials like Stainless Steel 316 or coated Carbon Steel, specifically selected to withstand saltwater spray, high humidity, and the thermal cycling typical of marine HVAC applications.
- Integrated Electric Actuator for Seamless Automation: Equipped with a high-torque, waterproof electric actuator (IP67 or higher rating available), enabling reliable remote on/off or modulating control. It interfaces effortlessly with your ship's central control system, allowing for automated sequences and status feedback.
- Bubble-Tight Shut-off for System Integrity: Features a precision-machined ball and advanced seat materials (PTFE or metal-seated for higher temperatures) to ensure zero-leakage shut-off, crucial for maintaining system pressure and preventing cross-contamination between circuits.
- Low Torque & High Cycle Life: The quarter-turn design and low-friction seats ensure minimal operating torque, reducing actuator load and energy consumption while supporting millions of reliable cycles, minimizing maintenance needs.
- Versatile Configuration & Mounting: Available in a wide range of sizes (DN15 to DN300) and connection standards (flanged, threaded, welded) to integrate perfectly into new builds or retrofit existing shipboard piping systems.
To provide a clear overview of the standard options, here is a summary of key specifications:
| Parameter | Specification / Options |
|---|---|
| Valve Body Material | Stainless Steel 316/316L, Carbon Steel WCB/WCC, Duplex Steel |
| Actuator Type & Protection | Electric (On-Off or 4-20mA Modulating), IP67, IP68 optional |
| Pressure Rating (PN/Class) | PN16, PN25, PN40 / Class 150, Class 300 |
| Temperature Range | Standard: -20°C to 150°C; High-temp seats: up to 180°C |
| Connection Standards | Flanged (JIS, DIN, ANSI, GB), Threaded (NPT, BSPT, BSPP), Butt-Weld |
| Control Signal & Power | 24V DC, 110V AC, 220V AC; Feedback: Potentiometer, Limit Switches |
The integration of this valve into your ship's HVAC system brings tangible benefits:
- Enhanced Operational Safety: Eliminates the need for crew to access remote or hazardous valve locations for manual operation, reducing risk.
- Improved System Efficiency & Energy Savings: Enables precise and rapid control of chilled water, seawater cooling, and air handling flows, optimizing the entire HVAC plant's performance.
- Reduced Maintenance & Lifecycle Cost: The durable design and reliable actuation significantly lower the frequency of repairs and replacements, offering a strong return on investment.
- Simplified Integration & Compliance: Designed to meet common marine standards, our valves facilitate easier integration with ship automation systems, aiding in overall compliance with modern vessel design principles.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for both seawater and freshwater applications in the HVAC system?
A: Absolutely. The valve is constructed from marine-grade corrosion-resistant materials like Stainless Steel 316. When specified with appropriate seat materials (such as PTFE), it is perfectly suitable for controlling seawater for cooling coils as well as chilled or hot freshwater within the HVAC circuit.
Q2: Can the electric actuator be configured for both on/off and flow modulation control?
A: Yes. We offer two primary actuator variants. The standard version is for simple on/off operation. For applications requiring precise flow control (like modulating chilled water supply), we provide actuators capable of accepting a 4-20mA control signal for proportional positioning.
Q3: What is the ingress protection (IP) rating of the electric actuator, and is it sufficient for marine environments?
A: Our standard electric actuators typically feature an IP67 rating, meaning they are dust-tight and can withstand temporary immersion in water. For more demanding locations, such as open deck or high-splash zones, IP68-rated or even explosion-proof versions are available upon request.
Q4: How does the valve integrate with my ship's existing control or automation system?
A: Integration is straightforward. The actuator receives a power supply and a control signal (simple contact closure for on/off, or 4-20mA for modulating) from your control panel or PLC. It also provides position feedback signals (like limit switches or a potentiometer) that can be wired back to the control system for status indication.
Q5: Are spare parts readily available, and what is the typical lead time for an order?
A: As the manufacturer, we maintain an inventory of critical spare parts like seals, seats, and actuator components. Standard valve sizes and configurations often have shorter lead times, while customized orders may require additional production time. Specific timelines can be provided upon inquiry.
Q6: Do you offer valves with different connection standards to match international piping?
A: Certainly. To serve our global clientele, we manufacture valves with flanges conforming to JIS, DIN, ANSI, and GB standards, as well as various threaded (NPT, BSP) ends. Please specify your required standard when requesting a quotation.
Q7: What maintenance does this valve and actuator require?
A: The design prioritizes low maintenance. The actuator is generally maintenance-free. The valve itself may require periodic inspection of stem seals and, after extended service, potential seat replacement. The full-quarter-turn design and robust construction contribute to a long service interval.
Q8: Can you provide custom configurations, such as special coatings or materials?
A: Yes, customization is a key part of our service. We can work with you on special material selections (like duplex steel), coatings (epoxy, galvanization), actuator specifications, or mounting brackets to meet the exact needs of your project.
