As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve is dedicated to providing reliable fluid control solutions for demanding marine environments. Our Marine High Pressure Ball Valve, PN100 DN50 with flanged connection, is engineered to withstand the harsh conditions of offshore and shipboard applications. With an annual export value reflecting our global reach across North America, South America, Europe, Asia, and Africa, we have built a reputation for delivering valves that combine robust construction with precise performance. This valve is specifically designed to offer secure shut-off and flow control in high-pressure seawater, fuel, and other critical marine piping systems, ensuring operational safety and longevity for your vessels and offshore platforms.
This valve stands out due to its specialized design considerations for marine use. The key characteristics and technical advantages are detailed below:
- Corrosion Resistance: Available in materials like stainless steel 316 or duplex steel, offering superior resistance to saltwater corrosion, a critical factor for marine longevity.
- High-Pressure Integrity: Rated for PN100 (Class 600), it reliably contains pressures up to 100 bar, making it suitable for main seawater lines, high-pressure washdown systems, and fuel transfer lines.
- Robust Flanged Connection: The flanged ends (RF or RTJ) provide a strong, leak-proof connection that is easy to install, maintain, and inspect, which is standard in marine piping.
- Bubble-Tight Shut-off: Features precision-machined ball and seat assemblies, often with reinforced PTFE or metal seats, ensuring zero leakage even after prolonged cycling.
- Low Torque Operation: The trunnion-mounted or floating ball design reduces operating torque, allowing for smoother actuation with manual levers, gear operators, or automated actuators.
- Extended Service Life: Internal components are designed for minimal wear, and stem seals are often multiple for added safety, reducing maintenance intervals and total cost of ownership.
The technical specifications for the standard DN50 model are summarized in the following table:
| Parameter | Specification |
| Size (Nominal) | DN50 (2" NPS) |
| Pressure Rating | PN100 / Class 600 |
| Connection Standard | ASME B16.5 / EN 1092-1 Flanges |
| Body Material Options | WCB, CF8M (316SS), Duplex 2205 |
| Ball & Stem Material | Stainless Steel, with optional coatings |
| Seat Material | PTFE, RPTFE, Metal (Inconel) |
| Test Standards | API 598 / ISO 5208 |
For clients, the primary benefits translate into tangible operational advantages. The valve's reliability minimizes the risk of costly downtime and hazardous leaks at sea. Its compatibility with various actuation methods allows for integration into automated control systems, enhancing operational efficiency. The standardized flanged design simplifies inventory management and replacement procedures. Furthermore, the selection of appropriate materials for specific media (e.g., seawater, oil, chemicals) ensures optimal performance and system integrity over the long term.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for seawater service?
A: Yes, it is designed for marine environments. We recommend specifying materials like 316 stainless steel or duplex steel for optimal corrosion resistance against seawater.
Q2: What flange standards are available?
A: The valve is typically supplied with ASME B16.5 Class 150/300/600 RF flanges or equivalent EN (DIN) standards. Other standards like JIS are available upon request.
Q3: Can this valve be supplied with an actuator?
A: Yes. The valve is designed to be easily fitted with pneumatic, electric, or hydraulic actuators. We can provide the valve as a package with a suitable actuator based on your control requirements.
Q4: What is the lead time for a standard DN50 PN100 valve?
A: For standard material configurations, lead times are generally competitive. Exact timelines depend on current order volume and specific material selection, which we can confirm upon inquiry.
Q5: Do you offer fire-safe versions of this ball valve?
A: Yes, fire-safe design compliant with standards like API 607 or API 6FA is available as an optional feature. Please specify this requirement when inquiring.
Q6: What are the testing procedures before shipment?
A: Every valve undergoes rigorous pressure testing (shell test and seat test) per API 598 or ISO 5208 standards. Test reports can be provided.
Q7: Is the valve suitable for cryogenic service?
A: The standard temperature range is -29°C to 200°C. For lower temperature applications (cryogenic service), special design considerations and material treatments are required and can be discussed.
Q8: Do you provide customization for different end connections?
A: While flanged connection is standard for this model, other end types like butt-weld ends can be explored for custom orders based on project specifications.
