★     1, Constructurely adopt the theory of pressure difference auto lock,

            can bear huge water pressure in water pipe, compared with other

            valves in the market , our valves ae suitable for high water pressure.

★     2, It's very flexible and sensitive to switch the water, a few strength

            need to close the water.

★     3, Another artribute of our valves is that unit water flow rate is very

           quick among so many valves in the market, size of valves is smaller
