 In the selection of the electromagnetic pulse valve, the output voltage can meet the requirements, the cleaning effect of the pulse three way position  has a larger impact in the selection of the control device, in particular, DC24V control device, to determine whether the controller sent enough voltage and current is very important, now two cases to analyze:

A high-power tube output of the control instrument in the output voltage at both ends of the electromagnetic pulse solenoid operated valve  controller output voltage and high-power tube voltage drop, so the analysis to control the instrument circuit design parameters to determine whether side of the chaos of DC 24V is very important.

2, the relay output control device of the control instrument because the voltage output through the relay contacts, there is no pressure drop, so as long as the power sector of the controller design fair, the normal output is no purpose.
