Shanghai Zhibang Valve Manufacture Co., Ltd., an ISO9001-certified manufacturer established in 2016, specializes in high-performance marine valves. Our CB/T4480 Marine Bronze Electric Ball Valve is designed for on-off control applications on cargo ships, fishing vessels, and other marine platforms. Combining robust bronze construction with reliable electric actuation, this valve ensures precise flow control, corrosion resistance, and long service life in harsh marine environments. With an annual export value of US$1–1.5 million, we serve global markets including North America, Europe, Southeast Asia, and the Middle East. Our commitment to quality and customer satisfaction makes this valve a trusted choice for shipbuilders, fleet operators, and marine engineers.
This electric ball valve fully complies with the CB/T4480 marine standard, guaranteeing dimensional consistency and interchangeability. It features a full-bore design for minimal pressure drop and smooth flow, and the electric actuator provides quick, reliable on-off control with manual override capability. The valve body is made of high-strength bronze (e.g., tin bronze or aluminum bronze) that resists corrosion from seawater, oil, and other marine fluids. The trunnion-mounted ball and PTFE seats ensure tight sealing even under low pressure, while the actuator is IP65/IP67 rated for protection against water and dust ingress.
