Marine flange type manual operated butterfly valve

1.For gasoline and other medium which temperature from 80℃ and 170℃, only the”FPM” can be used.

2.The valve is applicable to industrial of shipping,petroleum,chemical engineering, metallurgy,food etc.

3.Fluid cutoff: The opening and closing of the valve can be achieved by rotating the valve plate, thereby controlling the on - off of the fluid in the pipeline. This is convenient for the maintenance and repair of various pipeline systems, or for stopping the operation of certain systems as needed. For example, in the seawater cooling system of a ship, when it is necessary to repair the cooling pipeline or related equipment, the double - flange butterfly valve can be closed to cut off the flow of seawater, ensuring that the maintenance work can be carried out safely in a water - free environment.

4.Flow regulation: By changing the opening degree of the valve plate, the flow rate of the fluid in the pipeline can be adjusted. For example, in the fuel supply system of a ship, according to the load of the engine and the actual operation requirements, the double - flange butterfly valve can be used to accurately adjust the fuel flow rate to ensure that the engine receives the appropriate fuel supply and maintain its stable operation.

5.Flow direction control: With the cooperation of other valves or pipeline layouts, the marine double - flange butterfly valve can also control the flow direction of the fluid, making the fluid flow between different pipelines or equipment according to the design requirements. For example, in the ballast water system of a ship, by operating the double - flange butterfly valve, the ballast water can be guided into different ballast tanks to achieve the balance adjustment and stability control of the ship.
