As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for the demanding marine industry. Our High Pressure Marine Ball Valve is engineered specifically for ship HVAC systems, offering exceptional performance under PN2.5MPa pressure with a flanged connection for secure and leak-proof installation. With years of expertise since 2016 and a significant annual export value, we understand the critical need for durability and safety in marine applications. This valve is designed to withstand harsh sea environments, ensuring the smooth operation of your vessel's heating, ventilation, and air conditioning systems.
This high-pressure ball valve is a cornerstone for reliable marine piping. Its design prioritizes longevity and minimal maintenance, crucial for operations far from shore. Below are the key features and technical specifications that set our product apart.
- Superior Pressure Handling: Rated for PN2.5MPa (approximately 363 psi), this valve is built to manage the high-pressure demands of centralized shipboard HVAC systems without performance degradation.
- Robust Construction for Marine Use: Manufactured from corrosion-resistant materials like stainless steel or specially coated carbon steel, it effectively combats saltwater spray, humidity, and other corrosive elements prevalent in marine environments.
- Reliable Flanged Connection: The flanged end connection ensures a strong, bolted joint that is easy to install, inspect, and maintain, conforming to international flange standards for compatibility with existing ship piping.
- Bubble-Tight Sealing: Advanced seat materials, such as reinforced PTFE or metal seats, provide a bubble-tight shut-off, preventing any leakage of water, refrigerant, or air in the HVAC circuit, which is vital for system efficiency and safety.
- Full Port Design: The full-bore design minimizes pressure drop across the valve, allowing for maximum flow capacity and reducing pumping energy requirements for the HVAC system.
- Versatile Actuation Options: Available with a standard manual lever, gear operator for high-torque applications, or automated with pneumatic/electric actuators for integration into remote control systems.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for seawater service in the HVAC system?
A: Yes, when ordered with appropriate corrosion-resistant materials like 316 stainless steel or duplex steel, it is well-suited for handling seawater or brine in cooling circuits. -
Q: What flange standards do you comply with?
A: Our flanged valves are manufactured to common standards such as ANSI B16.5, DIN, JIS, or GB, depending on customer specification. The face-to-face dimensions typically follow API 6D or ASME B16.10. -
Q: Can this valve be supplied with actuators for automated control?
A: Absolutely. We offer optional pneumatic (double-acting or spring-return) and electric actuators. Please provide your required voltage, torque, and control signal for a precise quote. -
Q: What is the lead time for a typical order?
A: For standard specifications and materials, lead time is generally 4-6 weeks. Customized requirements may extend this period slightly. -
Q: Do you provide fire-safe certified valves?
A: Fire-safe design compliant with API 607 or API 6FA standards is available as an option for applications where this is a critical safety requirement. -
Q: How do you ensure quality control?
A: Every valve undergoes rigorous testing, including shell test, seat test, and operational tests, in line with our ISO9001 quality management system. Test reports can be provided. -
Q: What is the main difference between PN2.5MPa and Class 150/300?
A: PN2.5MPa is a metric pressure rating (~25 bar). Class 150 and Class 300 are ANSI pressure class ratings. PN2.5MPa is roughly equivalent to both, depending on the material group and temperature; we design to meet the requirements of these common classes for marine use. -
Q: Can you provide valves with special coatings or painting for extra corrosion protection?
A: Yes, we can apply epoxy coatings, zinc plating, or other protective finishes as specified by the customer to enhance durability in aggressive marine atmospheres.
