Electric Actuator Fast-closing Electric Actuator DC24V/DC220V Electric Actuator
The fastest switching time of fast-switching electric actuator is 5S.
I. Overview of Fine and Small Valve Actuator Products

EOA imported series electric actuators are suitable for some rotary valves (such as butterfly valves, ball valves and dampers). Imported electronic components, high-quality aluminium alloy die-casting shell, fine and smooth, small size, light weight, maintenance-free, strong corrosion resistance and other excellent performances can be used in narrow areas. Products are widely used in building automation, water conservancy, papermaking, power, chemical and other automation control systems. Its specific advantages are as follows:
The shell is small and smooth, small in size, light in weight, simple in wiring, beautiful and easy to move and maintain.
(2) The performance is superior, stable and complete, including general type, potentiometer type, passive type, intelligent type, fast and slow switch, indicator display and so on.
(3) The power loss rate is low, which can save a lot of cost.
(4) Advanced technology, stable performance of imported original parts in electronic part, fine and precise processing of mechanical part, wear-resistant, with multiple protective devices to avoid damage caused by improper operation or overload, manual electric device can be controlled at any time, compact structural optimization eliminates the shortcomings of large working noise.
_Intelligent integrated device has 4-20mA. DC input and output signals which can be controlled by computer PLC and DCS system. Proportional adjustment control and positioning can be achieved without manual control. It can position self-locking, simple connection, stable and reliable performance, high control accuracy and fast reaction speed.
It is convenient to install on the valve, but it can be directly installed on the manual valve without mechanical processing.
_Voltage has AC220V, DC220V, DC24, AC110V and other power supply can be provided.


2. Outline Dimensions, Installation Dimensions and Wiring Diagrams of Fine and Small Valve Actuators
Matters needing attention:
1: Be sure to connect the wrong power supply phase sequence, so as not to damage the valve or actuator.
2: Manual operation is prohibited when power is on.
3: When used outdoors, it is better to add protective cover to the electric actuator to prevent aging.
4: After opening the cover, tighten the screw to prevent water or dust from entering the inside of the executive body.
5: Please do not install around explosive gases.
6: Make sure the input voltage and wiring connection are correct.
7: It is forbidden to use electric actuator under overload.
8: Our factory does not accept any responsibility for improper alteration and maintenance of executing agencies.
