★Beautiful appearance, compact structure, high strength, zero leakage
    This valve with an innovative optimized design by three-dimensional model of CAD has a beautiful and compact appearance and modern modeling, and adopts new material and new technology to ensure that the valve has the good quality, good product performance, more reliable, more economical, more durable, which is fully compliant with the latest technical specifications of international standard, and which is the first choice for future automation system.  
    With the full-size and floating ball structure, the valve can be shut off without leakage in the whole pressure range, which is convenient to pipeline pigging and maintenance.
    The compact and reasonable structure and the minimum space of bore reduce the medium retention. In addition, a special molding process ensures that the sealed surface presents good density, and even the herringbone ring PTFE packing assures the valve of zero leakage.
    ★Strong corrosion resistance, a broad scope of application
    The valve owns excellent corrosion resistance to chemical.
    The ball valve with FEP lining has high chemical stability, and is suitable for any strong corrosive medium except the "molten alkali metals and fluorine."
    ★Diversified performance, suitable for the transmission of mediums with large pressure drops and large temperature drops, convenient to install
    The ball body (headstock piece) and stem are cast or forged to a integrated structure together, which eliminates the possibility of the stem impacting to the pressure part caused by the pressure change, and fundamentally guarantees the use safety in project.
    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 to maintain.
    The valve has superior corrosion resistance to chemical.
    The clean and smooth pipe wall can transmit liquid with small friction resistance and adhesive force.
    The valve has the excellent aging resistance and UV resistance, which make the normal service life extend a lot than other pipeline systems.
    ★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.
    ★Simple structure, easy to operate ,high cost-effective.
    This fluorine anticorrosion electric control valve with the diversiform plug structure (V type, O type) is easy to realize the regulation and cutting off by two-position. It is direct connection between the valve and actuator.
    The electric actuators with servo system inside never need be configured with the servo amplifier, whose operation can be controlled by inputting 4-20mA signal and 220VAC power.
    The valve presents simple connection, compact structure, small resistance, stable and reliable action.
    The two-piece, three-piece structure can adapt to working conditions and the piping system with different requirements, and of them the three-piece ball valve allows the main body and the both sides bodies to be separated, so as to realize rapid replacement and maintenance online.
    ★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.
