motorized valve wiring
1, RD connect DC9-24V positive
2, BK connect DC9 ~ 24V-/ 4-20mA-/0-5V-/0-10V-
3 GR connect position input /control current +/ control voltage +(4-20mA, 0-5V, 0-10V)
4, YW connect ERR output ,OC output
5, WTconnectposition feedback ,OC output PWM signal


Current Control-------------------4-20mA
Voltage Control-------------------0-5v, 0-10v
Motor voltage-------------------5v
Control accuracy------------------- ±1%
Valve operate stages-------------------It should be able to control at 5% open , 10% open ....90% open and 100% open

What is Modulating valve 4-20ma 0-5v, 0-10v, PWM voltage of position frequency output?

When working voltage is:DC24v, Modulating valve 4-20ma 0-5v, 0-10v, PWM wire voltage Plus the voltage, usually 3v, 5v
