Product introduction
EAF series electric actuator with crankshaft and base realizes the gyration action of rotary stem motion when equipped with various damper stopper, the high-temperature butterfly valve, hydraulic coupler.
EAF series electric actuator with the advanced technology of a built-in intelligent control module, does not need to be matched with servo amplifier, and which realizes conveniently the control and operation via control signal 4~20mA input by PPD localization technology.
Product Characteristics
★The output device of the rocker and bracket for the actuator.
EAF series electric actuator with crankshaft and base realizes the gyration action of rotary stem motion when equipped with various damper stopper, the high-temperature butterfly valve, hydraulic coupler.
★Long service life
More than 50000 operation life without fault, keep your system operating safely and reliably
★The patent localization technology
The actuator with the unique PPD localization technology patent is equipped with the EA control module, which supports the various signals such as 4-20mA ,0-10V etc., and which can communicate directly with PLC control device.This actuator is convenient to precisely regulate the valve opening without manual operation.
★EA control module
EA control module technology is called electronic braking circuit with high precision and high reliable performance, which can be shut off instantaneously.
★Good sealing performance.
This actuator with high sealing standard immerses wholly in water with no air leakage .Especially suitable for outdoor conditions
