Some of the fancier valves have a feedback control where it knows if it can’t open or close the valve properly, and send an alarm to the control system. But this appears to be a typical older style valve that works just fine, but sometimes needs a little love to keep it working as it should.
is that two wire control ( on off) or 3 wire control ( proportional) actuator head? I also notice that you have a N/C valve. Where I live up north a lot of the heating valves are N/O so that if a failure happens it will force the valve into full heat. But that also depends if you have a direct acting or reverse acting actuator.
how would you prevent the valve from sticking in the future? is there any fix for it or is it just a maintainance point every once in a while, or is it something that happens as it gets close to time to replace it?
