Shanghai Zhibang Valve Manufacture Co., Ltd. is a professional manufacturer specializing in high-performance butterfly valves for marine and offshore applications. Our Butterfly Valve for FPSO Ballast Water and Bilge System Piping is engineered to meet the demanding requirements of floating production, storage, and offloading (FPSO) vessels. With over 8 years of industry experience and an annual export value of US$1–1.5 million, we deliver reliable, corrosion-resistant valves that ensure optimal flow control in ballast water and bilge systems. This valve combines robust construction, tight sealing, and long service life, making it a trusted choice for shipbuilders and offshore operators worldwide.
Key Features & Advantages
- High Corrosion Resistance: The valve body and trim materials are selected to withstand aggressive seawater, ballast water, and oily bilge water, reducing maintenance frequency and extending lifespan.
- Bubble-Tight Shut-Off: Precision-machined resilient seat (EPDM, NBR, or PTFE) with a concentric or double eccentric disc design ensures zero leakage at rated pressure, critical for environmental compliance.
- Compact & Lightweight: Wafer and lug configurations save space and reduce piping loads, ideal for confined FPSO machinery spaces.
- Easy Operation: Available with manual lever, gearbox, or actuated (pneumatic/electric) options to suit automated control systems.
- Low Torque & Low Pressure Drop: Streamlined disc profile minimizes fluid resistance, saving energy and optimizing system performance.
- Wide Size & Pressure Range: From DN50 to DN1200 (2"–48") and PN10/PN16/Class150, covering most ballast and bilge piping requirements.
- International Standards: Designed and tested in accordance with ISO9001 quality management system, API 609, and EN 593 standards (optional third-party certification available).

Application-Specific Benefits
- Ballast Water Systems: Our butterfly valve handles high flow rates and frequent operations with minimal wear. The EPDM seat resists seawater and biological growth, meeting IMO D-2 discharge standards indirectly.
- Bilge Water Systems: The valve’s tight sealing prevents oil and sludge leakage, ensuring safe transfer to treatment units. Optional wetted parts in stainless steel or duplex provide extra durability.
- FPSO Integration: Designed for easy mounting between flanges, the valve can be installed in both horizontal and vertical pipelines, and the actuated version integrates seamlessly with PLC control systems.
- Low Maintenance: Non-wetted stem design and replaceable seat reduce downtime. All materials are selected for long-term offshore service.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for both ballast water and bilge water?
A: Yes, the valve is designed for seawater, ballast water, and oily bilge water. The standard EPDM seat is excellent for water, while NBR or Viton can be selected for higher oil content. -
Q: What pressure rating is available?
A: Standard pressure ratings are PN10, PN16, and Class150. Higher pressures (Class300 or custom) are available upon request. -
Q: Can I get an actuated version with a pneumatic or electric actuator?
A: Absolutely. We provide manual gearbox, pneumatic (double-acting or spring-return), and electric actuators from trusted brands (optional). Actuator type and control voltage can be customized. -
Q: How long is the valve’s service life in FPSO environments?
A: With proper material selection (e.g., Ni-Resist ductile iron disc, stainless steel stem), the valve can last 10–15 years in typical FPSO conditions. The resilient seat is replaceable to extend service. -
Q: Do you provide certificates like ISO or material test reports?
A: Yes, the valve is manufactured under ISO9001 quality system. Material certificates, hydrostatic test reports, and dimensional inspection reports can be provided with each order. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes (DN50–DN300), MOQ is 10 pcs. For larger sizes or special alloys, MOQ can be discussed. -
Q: How do you ensure leak-tightness during installation?
A: The valve is tested at 1.5x the rated pressure for shell test and 1.1x for seat test (bubble-tight). We also provide installation guidelines and recommend proper gaskets and bolting torque. -
Q: Can the valve be painted or coated for extra protection?
A: Yes, we offer optional epoxy coating (e.g., fusion-bonded epoxy) or zinc-rich primer for enhanced corrosion resistance. Please specify when ordering.
