★Small opening torque, good seal performance, long service life
    The seal performance for two-ways between disc and seat is superior when the valve closed, and the torque is small.
    The friction between disc and seat is small.
    The valve is operated by the working principle that the shaft drives disc to rotate 90 degrees to realize flexible switch without jam, jumpiness.
    More than 50,000 operation life without fault, keep your system operating safely and reliably.
    The seal parts are made of PTFE to realize long service life. 
    ★Beautiful appearance, simple and 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 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.
    The body with split type structure, the sealing at the end of shaft is controlled by fluorine rubber and rotational surface between disc and seat, which makes the product has compact structure, beautiful appearance, reasonable technology, reliable performance.
    The structure ensures that the shaft is isolated with the fluid mediums in bore, which is very convenient to replace the shaft and the valve never needs be removed from the pipeline.
    The compact and reasonable structure and the minimum space of bore reduces the medium retention. In addition, a special molding process assures that the sealing surface presents good density, and the herringbone ring PTFE packing ensures that the valve achieves zero leakage.
    ★Strong corrosion resistance, a broad scope of application
    The valve owns excellent corrosion resistance to chemical.
    Using fluorine plastic lining technology, the body is cast by sophisticated fired mold, with high strength and smooth appearance.
   The flow-passage components contacted with liquid are fluorine plastic. Hence, it is suitable for the any concentration corrosive pipeline at -50 ℃ ~ 180 ℃ for a long term.
    This product with high chemical stability is widely used in various piping of liquid, gas including steam, especially suitable for strong corrosive medium such as sulfuric acid, hydrofluoric acid, phosphorus, chlorine, alkali, aqua regia and so on.
    The fluorine electric butterfly valve is designed to control, open and close various strong corrosive medium, and is widely applied in the field of petroleum, chemical-engineering, dyeing, manufacturing acid and alkali and so on, which is the most ideal choice for anti-corrosion equipment at present.
    ★Diversified performance, suitable for large pressure drops services and large temperature drops services, convenient to install.
    The body (headstock piece) and the stem are cast or forged to a integrated structure together, which eliminates the possibility of the stem impacting to the pressure parts caused by the pressure changing, 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.
    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 working principle of Fluorine Butterfly Valve: By rotating the disc to keep the valve flowing or occlusive. The inner side of disc and body all adopt fluorine plastic lining process, which has easy and convenient switch, small size, reliable sealing, simple structure, convenient maintenance, a broad scope of application and so on.
    ★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, small flow resistance, easy operation, high cost-effective.
    This fluorine 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 presents simple connection, compact structure, small resistance, stable and reliable action.The valve is accurately controlled via switch signal 4~20mA from industrial automation control system, which regulate and control the different technical parameters of the flow, temperature, pressure.
    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 fluorine 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.
    The disc adopts frame structure with high strength, large flow area, small flow resistance.
    With two-way sealing function, the valve doesn’t be affected by the spatial position and the flow of medium, and can be installed in any direction.
    This valve supports the unique structure, flexible operation, energy saving, convenience.
    ★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.
