Hello A.J,
     There are lots of ways to do this:

• One approach would be to use a 1min timer.  When the timer completes, lower the valve and start the timer again. (Timers like TON, TOF, OUT_T, etc.)
• Another approach would be to use PLC's internal system clock (SD214 - depending on PLC) and lower the valve when the value changes.

     Which PLC are you working with and what language are you programming in (ladder, FBD, ST)?

You need to add far more detail.

Analogue? Voltage/current . Many types of valves.

Too vague to answer yet.
