★Beautiful appearance, compact structure, small flow resistance.
    With an innovative optimized design by three-dimensional model of CAD, this valve has a beautiful and compact appearance and modern modeling, and adopts new material and new technology to ensure good quality, good product performance, more reliable, more economical, which is fully compliant with the latest technical specifications of international standard, and which is the first choice for future automation system.
    The valve presents the advantage of simple connection, compact structure, small size, light weight, small resistance, stable and reliable action.
    ★Strong corrosion resistance, a broad scope of application.
    The valve owns excellent corrosion resistance to chemical.
    ★Light weight, diversified performance, easy to install.
    With lightweight body and actuator, the valve has small volume, enough torque, excellent strength and toughness, abrasion resistance, convenient installation, easy maintenance and disassemble.
    The flame-retardant performance is realized by its self-extinguishing.
    The low thermal-conductivity performance equates about 1/200 of steel.
    The used material is health and non-toxic to comply with national health standards.
    The clean and smooth pipe wall can transmit liquid with small friction resistance and adhesive force.
    Compared with other pipeline systems, the excellent aging resistance and UV resistance ensures that the product’s normal service life is extended a lot.
    ★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 UPVC electric butterfly valve is applied in the occasion of regulating and cutting off by two-position. It’s 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 is accurately controlled via switch signal 4~20mA from industrial automation control system to regulates and controls the different technical parameters of the flow, temperature, pressure.
    ★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.
