1) The water on the surrounding environment without any pollution. Compared with mineral oil, pressure water valve and its low prices, high pressure filters storage and use of the time no environmental pollution and non-toxic, people can more readily and cheaper to use it propane high pressure regulator but also the product environment, such as cleaning rooms or cutlery. All the hydraulic mechanism of water leakage or overflow simply evaporate without leaving sticky, greasy, dirty, Slippery Remnant. As 85% of all hydraulic fluid eventually leave their system, through a slow leak, disaster-line fracture or failure of the parts and seals.
(2) the environment is not just talking about here is the Earth's environment,
(3) the water hydraulic machinery as a working medium, used in much lower costs than mineral oils. It will therefore be very effective in the hydro-mechanical long-term use water instead of oil.
(4) Water does not run out of resources, since water can be naturally recovered. Saline water component exists.
(5) tap water and health in industrialized countries. This means there will be negligible in leakage of product contamination case. Product compatibility, especially in the food, pharmaceutical and chemical industry, water hydraulic technology provides the benefits of hard to replace. . This is important to provide a system is the maintenance and well being contaminated and can be transmitted by the hydraulic mechanism on the surrounding bacteria. Pneumatics, which provides a possible option, but needs a little oiling lubricant mist, there are high-energy consumption, lower power density . However, the need to be careful if the water hydraulic mechanism is used in sensitive areas or near the variable leakage of sensitive machines will not be tolerated.
(6) The water is not flammable, it is difficult to form fire danger
(7) The use of water in the production line means that workers do not breathe in the harmful oil vapors inside or not subjected to skin and eye exposure to the steam.
(8) reduce insurance costs due to non-flammable and non-toxic
(9) Water is the thermal conductivity of mineral oil (Thostmann and Clausen 1995) 4-5 times, which means that water systems require less or no cooling fluid, which even further cost savings.
