★Long service life
    More than 50,000 operation life without fault, keep your system operating safely and reliably
    Because the special designed sealed parts are made of PTFE materials with good self-lubrication properties, the small friction loss with ball body ensures the ball valve a long service life.
    ★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.
    ★Miniature design, beautiful appearance, compact structure
    The valve with small volume is easy to install in any direction of the pipeline, which is suitable for various complex pipeline and working conditions.
    The valve with ultra-miniature volume weights 1.2Kg, whose height is less than 120mm.
    ★The actuator has  good pressure resistance performance, large torque, good seal performance.
    The EA series electronic actuator can go through 1500V high voltage test without power leakage, which ensures your system operate completely.
    This EA series electronic actuator with high seal standards can be immersed in water without air leakage, which is especially suitable for outdoor conditions.
    The full steel metal gear supports simple and reliable transmission structure (operation life greatly exceeds the plastic gear) and the worm wheel outputs the large torque.
    ★High adjustment precision, a broad scope of application.
    The valve has high adjustment precision, large adjustable ratio (Maximum 300:1), excellent adjustment performance to make it widely applied in various industrial fields for high precision adjustment.
    The series valves owns new technology patent for the valve core design, which is very suitable for various fields of tiny flow regulating and controlling.
    ★The valve owns a self-cleaning function, which can effectively guarantee the piping circulating.
    The valve can easily cut off all kinds of impurities in the pipeline, and effectively guarantees the pipeline circulating.
    The plug with self-cleaning function and a purging function for pipeline has large pressure drops resistance, which is not easy to block.
    The simple channel, compared with the S channel structure of solenoid valve, has small flow resistance and no block.
    ★Light weight, diversified performance, easy to install
    This valve has the self-lock function. (Self-keeping valve position).
    The actuator has enough torque, light weight, small volume and convenient installation.  
    The valve owns excellent strength and toughness, abrasion resistance, easy to disassemble, simple and easy maintenance.
    The regulating valve plug still contacts with the sealed surface in rotating. With the ball shut off, the valve produces a shear effect to make the particles adhesion decrease into the minimum.
    Compared with other pipeline systems, the excellent aging resistance and UV resistance ensures that the product’s normal service life is extended a lot than that of other pipeline system.
    The valve with simple structure and reliable performance is widely instead of various solenoid valves with small diameter.
    With the output signal of fully open & fully shut (NPN transistor, collector current)
    This product supports various power connections. （AC24V-260V）
    ★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.
