As a professional manufacturer based in Shanghai, China, Shanghai Zhibang Valve Manufacture Co., Ltd. has been dedicated to producing high-quality industrial valves since 2016. Our Butterfly Valve for Offshore Platform Ballast and Cooling Water Systems, API 609 is engineered to meet the demanding requirements of marine and offshore environments. With an annual export value of US$1 million to US$1.5 million, we serve global markets including North America, Europe, Southeast Asia, and the Middle East. This valve combines robust construction, precise flow control, and long service life, making it an ideal choice for ballast and cooling water applications.
Our API 609 butterfly valve is designed with a compact, lightweight structure that simplifies installation and maintenance on offshore platforms. It features a resilient seat design for bubble-tight shut-off, ensuring no leakage in critical systems. The valve body is available in ductile iron, carbon steel, or stainless steel, with disc options in stainless steel or coated materials for enhanced corrosion resistance. Whether for manual operation or automated control, this valve offers reliable performance under high pressure and temperature variations.
Key Features and Benefits:
- API 609 Compliance: Meets international standards for design, testing, and performance, ensuring compatibility with global offshore specifications.
- Corrosion Resistance: Available with EPDM, NBR, PTFE, or Viton seat materials, providing excellent resistance to seawater, chemicals, and cooling water additives.
- Bubble-Tight Shut-Off: Resilient seat design ensures zero leakage, critical for ballast system integrity and cooling water efficiency.
- Low Torque Operation: Optimized disc profile reduces operating torque, allowing for smaller actuators and lower energy consumption.
- Versatile End Connections: Wafer, lug, and flanged types available to fit various piping systems, with customizable dimensions upon request.
- Wide Size Range: From DN50 to DN1200 (2" to 48"), suitable for both small and large flow applications.
- Easy Maintenance: Modular design with replaceable seat and disc, reducing downtime and repair costs.
- Automation Ready: Compatible with pneumatic, electric, and hydraulic actuators for remote or automated control.

The butterfly valve's design incorporates a self-centering disc and a one-piece shaft for enhanced stability and reduced wear. For offshore platforms, where space and weight are critical, our wafer-type valve offers a compact solution without compromising performance. The lug-type version allows for easy isolation of downstream equipment, while the flanged type provides robust connections for high-pressure systems. All valves undergo rigorous hydrostatic and pneumatic testing to ensure leak-tightness and durability.
