★Good seal performance, long service life
    More than 50,000 operation life without fault, keep your system operating safely and reliably.
    The valve seat with PTFE seal ring has good seal performance, whose structure is easy to seal, and the seal capacity of ball valve increases with the increase of the medium pressure.
    The seal performance of valve stem is reliable, because the valve stem only rotates without doing the lifting movement so that stem filling materials is not easy to be destroyed, and seal capacity increases with the increase of medium pressure.With good self-lubrication properties, PTFE materials make small friction loss with the body, and then prolong the service life of ball valve.
    The convex step at head of bottom-up installed stem prevents stem from being ejected. When the fire accident broke the sealing of valve stem, a layer metal contact is formed between the convex step and valve stem to assure seal performance of valve stem.
    ★Small flow resistance, big flow capacity, suitable for complex working conditions, easy to install
    The ball valve is one of the least flow resistances in all valves, even reduced diameter ball valve, whose flow resistance is quite small.
    The thrust bearing reduces friction torque of stem to make stem operate evenly and flexibly for a long time.Ultra short face-to-face dimension electric ball valve adopts the integrated structure, whose rotation can be controlled by single phase power, and which is stronger, smaller, lighter, portable, simple configurement, big flow capability.
    The valve is very suitable for the occasion of high seal performance and big pipeline pressure drops to switch and cut off the medium of pipeline.
    Compared with the same specifications of the gate valve and globe valve, the ball valve is smaller, lighter and easier installation in pipeline.
    ★Simple structure, easy to operate, high cost-effective.
    The EA series of electric actuators and the stem have been connected and debugged well, then the stem is driven by electric energy to realize 90 ° gyration action of the ball body.
    The valve is accurately controlled via switch signal from industrial automation control system, which regulates and controls the different technical parameters of the flow, temperature, and pressure.
    ★Beautiful appearance, compact structure, various choices of sealed form
    This valve is an innovative optimized design by three-dimensional model of CAD, which has a beautiful and compact appearance and modern modeling.
    The series valves adopt new material and new technology including 4 sealed forms respectively elastic sealing, high temperature resistant digital polystyrene, hard alloy and industrial ceramics, which ensures that the product presents many advantages such as the good quality, good product performance, more reliable, more economical, more durable.
    The products are fully compliance with the latest technical specifications of international standard, which is the first choice for future automation system.
    ★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.
