As a leading manufacturer in the valve industry, Shanghai Zhibang Valve Manufacture Co., Ltd. brings you the Marine Ball Check Valve 1/2"-2" (DN15-DN50) – a threaded, cast iron solution designed to meet the rigorous demands of marine environments. Since our establishment in 2016, we have focused on producing high-quality valves that ensure reliable backflow prevention and smooth flow control. This ball check valve is engineered with precision, featuring robust construction and CCS/DNV type approval, making it a trusted choice for shipbuilding, offshore platforms, and various marine systems.
Our marine ball check valve offers exceptional durability and corrosion resistance in saltwater conditions. The cast iron body provides strength, while the internal ball mechanism ensures a tight seal and minimal pressure drop. Available in threaded connections (1/2" to 2" or DN15 to DN50), it suits standard piping systems with ease. With pressure ratings of PN16 and PN25, this valve adapts to different system requirements, delivering consistent performance under demanding marine operations.
Key Features & Technical Specifications:
- Material: High-grade cast iron body, with optional internal coating for enhanced corrosion resistance.
- Connection: Threaded (BSP or NPT available upon request).
- Pressure Ratings: PN16 (16 bar) and PN25 (25 bar) – suitable for low to medium pressure systems.
- Operating Temperature: -10°C to +80°C (standard), customizable for extreme conditions.
- Ball Material: Stainless steel or rubber-coated, ensuring leak-tight closure.
- Design Standard: Conforms to marine industry norms; CCS and DNV type approved.
