Product Description

200nm/400nm/600nm Torque Electric Actuator for control valve

Product introduction
EA series electronic type electric actuator is equipped with various segmental valve(ball valve, butterfly valve, plug valve.) to form industrial automatic control electric valve such as electric control valve, electric ball valve, electric butterfly valve and so on.
Without servo amplifier, EA 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.

Product Characteristics
★GRAT new technology patent for Potentiometer Positioning Device(PPD)
GRAT's own PPD patent has created a new mode of positioning by changing the drawspring into torsional spring to realize longer service life, higher positioning accuracy, simpler debugging and more reliable operation of actuator, also eliminated transmission clearance and reduced abrasion of electrical components and mechanical parts.

★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.
200nm/400nm/600nm Torque Electric Actuator for Control Valve

★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 technology
EA control module technology is called electronic brake circuit with high precision and high reliable performance, which can shut off in a twinkle.
★Miniature size
With small volume, light weight, this actuator is easy to install in any direction of pipeline, and meets the requirements of complex pipeline and situation.
★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.
★Small volume, large torque
The whole volume and weight is about 1/3 of similar traditional products, and presents small input power, large torque, small installation place, and convenient transportation.
★Strong motor 
The motor is designed according to the valve operating characteristics with high starting torque, low starting current and smaller rotation inertia. The stators winding with a inbuilt overheat protector (automatic recovery type) to stop the motor to protect whole set of equipment safety when the valve was blocked. 
★Precision gear This actuator consists of precision tangent multistage gear and shaft made of superior steel with heat treatment to present high strength, good abrasion resistance, and to withstand a long-term fatigue load. The gear mechanism is filled with molybdenum grease of imported food grade to complete the permanent lubrication without inspection or maintenance.
★Torque transmission output mechanism In any position, the valve can be locked by the worm gear and worm stem made of high strength special alloy materials by precision machining. The worm gear and output shaft is an integral structure to fundamentally eliminate torque transmission interval problem to ensure more reliable transmission.
★The screw won't off The design can prevent the parts from losing during disassembly.
★Mechanical limited device Mechanical stroke limit bolt made of stainless steel and a limited stopper can precisely adjust the actuator to be a required angle. In order to conveniently modulate, the bolt is at the outside of body, and which is locked at required position by stainless steel nut after finishing each adjustment. Limit angle is usually set to 0~900  in the factory.(Custom angle depends on the customer )
★Valve opening display. The lens and body is glued with glass adhesive of imported food grade, which has high adhesive strength, unpolluted products and high temperature resistant to effectively resist the corrosion from the rain and other severe environment.
★Manual handle Stainless steel handle can drive valve to rotate in debugging or power failure, S means shut, O meats open.
★Wiring interface Two G1/2 waterproof cable joint is respectively for power line and signal line to prevent interference.
★The micro switch The imported micro switches have contact quality, operating life, insulating performance.
★Precision potentiometer  The high precision potentiometer is from three the largest brands supplier in the world, whose service life has more than 100,000 times long, and which is specially suitable for small opening modulation to ensure the accurate regulation of electric valve.
★Control module The control module with resin package has the remarkable characteristics such as high decomposition degree, powerful function, anti vibration, long service life and high reliability.
★Servo  The inbuilt control module continuously compares the input signal with the potentiometer feedback signal to stop the motor at equilibrium, then output shaft make the valve hold on in the corresponding position until input signal is changed to ensure continuous precision adjustment of valve opening.
