I suppose Toro wouldn't approve but at some point the guy who owned this house before me put a Rain Bird ESP-8 control head in (digital, looks like it's circa mid-late 90s vs. 1970s for the valve). The ESP-8 is connected to a bank of solenoid controlled valves that look exactly like the valves at the bottom of this image you posted in another thread:Use your controller to further pinpoint the exact replacement. A normally-open type of controller has a line feeding it pressurized water, usually through a filter. That controller then applies water pressure to the valves. A pin-type controller has no pressurized water feed. Note the two-digit coding on those valves. Electric is 06 - pin-type is 00 - normally open is 01. Toro controllers would use that same coding.
