Marine Threaded Fire Hydrant Valve:

Installtion: Marine threaded fire hydrant valve is a valve that is connected to the hydrant pipeline on the ship through thread. Due to the limited space on the ship, installing the threaded hydrant valve can save space and easy to install.

Application: Threaded fire hydrant valve is suitable for small ships or ships that need to move frequently, simple operation and easy maintenance.

Marine Flanged Fire Hydrant Valve:

Installtion: Marine flanged fire hydrant valve is a valve connected to the hydrant pipeline on the ship by flange.

Application: Marine flanged fire hydrant valves usually have higher pressure resistance and higher flow rate, and are suitable for large ships or ships that need higher fire water requirements. Although relatively complex to install, the connections are stronger and suitable for ships with higher safety requirements.

Overall, marine threaded fire hydrant valves are suitable for small ships or ships that need to move frequently, and are easy to install; while marine flanged fire hydrant valves are suitable for large ships or ships that need higher requirements for fire fighting water sources, with higher pressure resistance and flow rate. 

The choice of which type of marine hydrant valve should be decided according to the specific conditions and needs of the ship.
