Hi v2comp,
I would study the documentation for your proportional valves. The valves I have used have had a 'sealing function' or 'cutoff' parameter which would completely close the valve if the PLC's analog output fell below a threshold.
I was controlling water. Gas is considerably more hazardous, so take care and consider employing the services of a qualified co...

dont know why it double posted, the other is a Koganei KFP050-2-30-FM-BR-02
High-precision Proportional Control Valve has been newly developed, which is optimum for the production lines, plants, etc of air, gas, liquid, etc. The stepless control is realized, which is necessary to control the flow rate of gas and liquid. Standard input signal can be selected from 4 to 20mA in current as wel...

I guess the Moderators dont want other equipment manufacturers product specifics listed on the forum, I guess I should have read that somewhere, but anyway, the two different proportional gas valves and controllers I have are:
1 ASCO 8202 posiflow 24vdc and its controller
2-Way, Direct Acting, Brass or Stainless Steel Bodies, 1/8" to 3/8" NPT.
Flow rates adjustable...
