Product name:

 DFZK Automatically adjust electric valve controller

Summarizes:

DFZK controller is automatically valve controller,with the outside or 4~20mA control valve opening current control valve controller,It constitutes together with the ordinary electric valve electric system adjustable,Its external input control current by a computer,PLC or automation devices(hereinafter referred to as control) for a given,Comparison of a given controller input current and the current valve position,to determine whether the valve until the valve opening movement and the definition of a given current opening line.

Technical details:

1,Voltage: 220V /50Hz , 380V/50Hz

2,Input control signal  4~20mA,Output impedance  ≤200Ω

3 ,Output feedback current  4~20mA,over-load capacity ≥250Ω

4,Working environment

 Environment Humidity  -10~+40°C

Resistance Humidity ≤80% (20°C±5°C)

Around does not contain strong corrosive,flammable and explosive media

5, Sensitivity and dead zone  Depending on the system to automatically adjust

Features1,Opening, input, digital display, automatic setting zero full degree. Valve opening, the valve clearance, auto/manual, torque/protection LED display  2,Key tone prompts; on, off to the torque protection and accident (motor overcurrent, motor over-temperature, stalling, etc) the protection of sound and light alarm (with silencers feature ) 3,On,off flash tips to work process.4,According to the external control inputs automatically adjust the valve opening. 5,Automatic phase sequence correction logic power6,Can according to customer requirements is factory-set electric valve by full off position when you start the open valve so that beyond the moment electronic device to the maximum torque to open valve (this feature may resolve valve long without fault stuck, etc)  you can according to customer requirements is factory-set electric valve by a non-full off position when you start the closing valve, which go beyond the trips to electric appliance close the valve of maximum torque (for wedge-shaped, metallic sealing valve is ideal) . 7,Outline and installation dimensions, detection tester for electronic circuit wiring and early-stage product fully compatible to older user model change
