In recent years, pump turbines have been increasingly used at hydroelectric power plants to effectively utilize surplus electricity at night. Along with this, the output of a single water turbine is determined by the surplus power, so there is a tendency for the capacity to increase, and the inlet valve also needs to be a large-diameter, high-pressure valve. On the other hand, in order to open and close the inlet valve, a large-capacity pressure generation device or pressure storage device is required, but if this is hydraulically operated, it will require additional equipment such as a pressure oil device and a pressure tank, as well as the installation of these. Floor space is required.

Alternatively, there is an advantage that the equipment for the pressure storage device and the installation area thereof are not required.

However, since the pressure source is water, the water required for control must be of good quality, and water purification devices such as strainers and settling tanks are installed to ensure smooth operation of control equipment. We manufacture various switching valves, etc. using materials with anti-rust properties.
However, in the case of highly acidic river water (dam water), rust and corrosion occur in control equipment, which impedes smooth operation of the equipment and makes it impossible to control the opening and closing of inlet valves. Ta.
