For waterproof disaster preventionDesign & Manufacture of Water Hydraulic Cylinders For Opening & Closing Disaster Protection Water Barriers

Water pressure cylinder for waterproof gates for disaster prevention

These are water hydraulic barriers that use tap water to move. We developed them while focusing on direct and simple operation.
When you turn the lever to “Raise”, tap water pushes the piston inside the cylinder, propping up the water barrier panels.
When you turn the lever back to “Drop”, tap water pushes the piston inside the cylinder, bringing down the water barrier panels.
It doesn’t use any electricity and moves by relying only on the pressure of the flowing tap water.

Water Barrier Manufacturer:Ironworks Une Co., Ltd.

Special Features of the Opening & Closing Device on the ADS Water Barrier

Installing water barriers using the device at underground car park entrances and the like
will help you prepare for floods caused by sudden and heavy rains, typhoons, high tides, and tsunami.

No electrical power needed Since the device uses pressure from water in the water supply piping to prop up and bring down the water barrier panels, it can still function during emergencies and power outages.
User Friendliness Its operation only involves a lever, making it very simple and straightforward.
Manual Recovery Even if you can’t use pressure from the water pipes, the device has an assisting feature where you can use the manual recovery mechanism (a hand-pressed air pump).

For food processing machineryDesign & Manufacture of Water Hydraulic Cylinders For Food Processors, Meat Slicers & Presses, and Other Machines

  • Better food sanitation
  • Enables the cleaning of the entire food processor

*Regular food processors use pneumatics or electricity
 which require that cleaners avoid those areas when washing the device.

Water hydraulic cylinders can be washed, making them perfect for environments that require good hygiene.
They can be used for meat and other food processors
