★Long service life
    More than 50,000 operation life without fault, keep your system operating safely and reliably.
    The newest driver technology of quick switch electric actuator makes the valves have no power consumption at idle time, and need a little of electric power only at work, which effectively reduces the operation cost of system.
    ★The patent positioning technology
    PPD positioning technology completely solves the problem of poor positioning accuracy and a major application difficult of long time reliable operation.
    ★Short switch time
    The valve can complete the switch action in 3~4s.
    ★Large allowable pressure drops
    The pressure drops resistance reaches more than 1.0Mpa.
    ★The valve owns a self-cleaning function to effectively guarantee the piping circulating.
    The valve can easily cut off all kinds of impurities in the pipeline to effectively guarantee the pipeline circulating.
    ★Good seal performance, zero leakage
    The valve with two-sided sphere seal function can reach zero leakage.With the whole baking finish surfaces, the valve can effectively prevent rusting, and is suited to different medium when better seal rings or seal materials are assembled.
    ★Widely adaptability, various connection mode (flange type, wafer type, double plastic union etc. )
    This valve presents small volume, light weight, reliable performance, simple configurement.
    Body is matched with a standard convex pipe flanges.
    ★Simple and reliable straight-through structure, free to maintain.
    Compared with the S channel structure of solenoid valve, the simple channel has the advantages with small flow resistance and no block.
    The valve never needs maintenance from the beginning of first operation.There is no material accumulation near the body.
    ★Small flow resistance, big flow capacity, suitable for complex working conditions, easy to install
    The ball valve is one of the least flow resistances in all valves, even reduced diameter ball valve, whose flow resistance is quite small. 
    The thrust bearing reduces friction torque of the stem, and can make the stem operate evenly and flexibly for a long time.
    ★The new technology for Direct Debugging Switch(DDS) in electric actuators.
    Easy to use! Design by GRAT in China.
    It completely solved the problem of complex debugging and make the technology simpler.
    The debugging can be simplified from 5 steps to 1 step.
    The debugging for electrical and mechanical position can be easy achieved through rotating the knob on the top of the dial after electric actuators and valves are assembled together.
