Control board
Product specifications
Automatic control:
· 1.input signal: DC 4-20mA
· 2.Output signal: DC 4-20mA
· 3.Operate direction: standard positive function:4ma counterclockwise rotation, valve is close,20ma clockwise vavle is open
· nonstandard reverse action: 4ma clockwise rotate, vavle is close; 20ma counterclockwise rotation, vale is open.
· 4. State of fault signal: standard: when loss 4-20ma signal, the actuator keep normal position. · Nonstandard: standard: when loss 4-20ma signal, the actuator is close · Nonstandard: standard: when loss 4-20ma signal, the actuator is open
· 5.Dead zone: Though the dead zone to adjust potentiometer (P3),dead range:0-3% mean 0-480uA
· 6. This machine is run manually: This machine is run manually that make locator simulate a 4-20ma input signal, make actuator running.
Remote control · 1. Remote control for the passive dry contact control, Under the dry contact control, can make the actuator receives the remote switch command, complete valve opening and closing, the remote control is prior to the automatic control, when the controller is in remote position, the automatic control will be closed, which doesn't work
· 2.the running direction of actuator · Standard form: actuator(facing the output shaft) Clockwise to open it, counterclockwise to close it.
· Nonstandard form: actuator(facing the output shaft) Clockwise to close it, counterclockwise to open it.
· 3. The electric brake configuration
· One phase(220v AC) Configuration of electric braking complete by dial the code switch Three phase(380v AC) the plate electric braking function doesn't work through dial the code switch , actuator electric braking performed by external circuit.
· LED indication:(lining)
· LED1(green)the actuator is open
· LED2(red)the actuator is close
· LED3(green) open lead limit
· LED4(red)close lead limit
· LED4(yellow)over-torque on-off action
· LED6(red)loss 4-20ma signal
· LED7(green) electric braking doesn't work(pay attention: when in 3phase, electric braking doesn't work)
· LED8(red)power indicator

Company History
2014 Our company was registered in a rental house at the same time,the foreign trade department was established.
2015 The office address was changed to:Zhongbei Town Energy Saving Building this year our company has done 9000 certification CE certification and other qualification certifications, and the main export countries are southeast Asia, Parkistan Vietnam,Singpore and Thailand.
2016 The foreign trade business gradually increased exporting to South America Chile, Paraguay, Russia and other countries at the same time on the previous basis.
2020 Our company independently developed electric actuator sand applied for utility model patents and appearance patent certificates. The domestic and foreign trade business has grown rapidly,and the domestic trade department has been shortlisted as a fixed supplier for large enterprises such as Sinoma.Red Lion and Huaxin etc.The foreign trade department has been shortlisted as a fixed supplier for large enterprises such as Sinoma.Red Lion and Huaxin etc.The foreign trade department has undertakenmajor projects such as large-scale sewage treament.
2021 The annual sales volume of our companys electric actuators has approached 2,000units At the same time the following export qualifications have been handled:ROHS SILATEX etc,among them,the explosion-proof products have also passed the certification of the National Institute of Explosion-proofing.The main products have also passed the authoritative quality.
