★Small volume and light weight, easy to disassemble and maintain, and can be installed in any position
    The valve supports non-pin structure to effectively avoid the pin break off in a long time operation.
    With simple and reliable working principle, the body can be installed in the least space.
    With two-way sealing function, the valves can be installed in any direction and not be affected by the spatial position and the medium flow.
    ★Small pressure drops, Large flow capability
    This valve has the large flow capability, and very small pressure loss.
    The disc supports frame structure with high strength, large flow area, and small flow resistance.
    ★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.
    ★Small operating torque, energy saving.
    The valve has small volume, light weight, reliable performance, simple matching, large flow capacity, especially suitable for the medium such as clean liquid and gas.
    Configured with a convex pipe flanges, the body has high cost-effective, especially large diameter butterfly valve (prefer to butterfly valve in the occasions of middle and low pressure), the butterfly valves have superior cost-effective performance to realize a broad scope of applications.
    ★Linearity flow characteristics, the best control performance
    The valve with the approximate EQ% flow characteristic can be used to regulate or switch control.
    ★Simple and compact structure, 90° gyration to open quickly.
    The solid state electronic type electric actuator supports the electrical integration structure to realize the functions including the machine internal servo operation, opening signal location feedback, position indication, manual operation and so on.
    The valve has powerful function, reliable performance, simple connection, accurate control, small volume, lightweight, small flow resistance, big flow coefficient, simple structure, good seal performance.
    With a large modulation range, the valve can change the input current or voltage signal to corresponding displacement, so as to change the rotation angle of the disc (any angle from 0 o to 90o). Hence, a certain input signal is corresponding to a certain rotational angle to realize the proportional action, which has better regulation & control of flow parameters.
    ★Long service life, good seal performance.
    More than 50,000 operation life without fault, keep your system operating safely and reliably.
    The seal parts materials are mate of stainless steel and nitrile oil-proof rubber to extend service life.
    The plastic seal ring can be located not only on the body ,but also on the disc, which is suitable to the different characteristics of the medium according to the customers’ selection.
    With the whole baking finish surfaces, the valve can effectively prevent rusting, and is suited to different medium by changing better seal rings or seal materials.
    ★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.
