• Subsea Hydraulic Butterfly Valve   
    The subsea Hydraulic Butterfly Valve are commonly seen on the Ballast Tank of a ship, it can be used under sea water of 30 meters, and can be immersed in the water all the year around.
    Here, question is, the valve is installed under sea water, how do we operate it?
    Now, we have to introduce that Hydraulic Actuator, which is mounted on top of the valve, this can also be immersed under the sea water. Driven by the Hydraulic oil pressure which is acquired from the ship hydraulic system, and it can be either a Single Acting or Double Acting actuator, depends on client requirements.
