Classification: Actuator
Product Name: EAF Series Electric Actuator
Product Description:
With crankshaft and base, EAF series electric actuator is equipped with various damper baffle, high-temperature butterfly valve, hydraulic coupler to realizes the gyration action of rotary stem motion.
Without servo amplifier, EAF series electric actuator adopts advanced technology of a built-in intelligent control module to realize conveniently control and operation via 4~20mA control signal of PPD positioning technology.
★The holder of actuator and rocker output device
With crankshaft and base, EAF series electric actuator is equipped with various damper stoppers, high-temperature butterfly valve, hydraulic coupler to realizes the gyration action of rotary stem motion.
★Long service life
More than 50,000 operation life without fault, keep your system operating safely and reliably
★The patent positioning technology
With the unique PPD positioning technology patent and EA control module, the actuator supports 4-20mA, 0-10V signal and can be communicated directly with PLC to realize precise &convenient regulation of valve opening without manual operation.
★EA control module
EA control module technology is called electronic brake circuit with high precision and high reliable performance, which can shut off in a twinkle.
★Good seal performance.
Seal standard: This actuator wholly immerses in water with no air leakage, and is best suitable for outdoor conditions.
★Good reliability
The electrical components and precision parts are made of imported material to effectively ensure high quality and reliability of the product.
★Good pressure resistance performance
EA series actuator has passed through 1500V high-pressure resistance test without electric leakage to ensure your system operating safely.
★High modulation precision
The valve has high modulation precision, large rangeability (Maximum 300:1), and excellent modulation performance to bring a broad scope of industrial applications.
★The new technology for debugging and control device 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.
