The products come in two main structural configurations—straight-through (Type A/AS) and angle (Type B/BS)—fully accommodating diverse piping layouts in ship engine rooms, on decks, and at bulkheads. Primarily used to control the flow of water in fire-fighting lines, they allow for the rapid connection of fire hoses and nozzles to facilitate emergency shipboard firefighting, while also supporting deck-washing water supply functions.

Bronze Body Material

The valve body is cast from high-quality marine-grade bronze using a one-piece molding process, offering excellent resistance to seawater corrosion, salt spray, and oxidation. Featuring a robust structure and superior sealing performance, the valve resists rusting and leakage during prolonged maritime use. It is a specialized safety valve for marine fire-fighting systems, available with inspection certificates from major classification societies (such as CCS, ABS, and BV) to meet the class certification requirements of various vessel types.
