I have a Rainbird APAS-100 which has stopped consistently opening when powered.
I've isolated the problem to something in the "AVA-1 Actuator & Piston Assembly" – Rainbird part 145235. However, trying to locate the replacement part (or an entire replacement valve to harvest parts from) has been fruitless; the APAS-100 and APAS-075 have been long-since discontinued and I cannot find any source of parts.
What can I do to get a working valve in place without the headache replacing the entire valve assembly?

Champion Irrigation makes a valve called the PCL-100 which is compatible with the body from the APAS-100 (and a PCL-075 which ought to fit the body of the APAS-075), which are available as of this writing.
The specific part that I got is the PCL-100-C (not sure what the C means and if the B model works in the same way).
The valve fit perfectly onto the APAS-100's body (though the wires from the solenoid were a bit of a tight fit when installing, I had to take some parts off the neighboring valve to get it screwed on). In initial testing, it seems to function just fine on the APAS-100's body.
