Technical Field

The invention relates to a manual-automatic integrated hydraulic driver for a marine valve and a driving method.

Background

With the continuous development of industry, hydraulic transmission is widely applied, and the requirements on safety and reliability of hydraulic drive are continuously improved. The wide application of the large-diameter valve on the marine vessel ensures that the torque required by the opening and closing of the valve is larger and larger, and the reliability requirement is also continuously improved.
