Often times people follow the saying, “if at ain’t broke don’t fix it” which in the case of the Maxton UC3 elevator control valve is not the safe, energy efficient, or cost effective decision for a number of reasons. First off, the UC3 valves are over 37 years old well beyond its intended useful life and Maxton’s suggested 5 year overhaul or replacement cycle with at least some adverse conditions in most installations. Second, the system using a UC3 is lacking optimal operation and energy saving features which come from new parts and innovations built into the current replacement UC4 series valve designs. Lastly, by not following the preventative maintenance approach and 5 year cycle, the system will experience potentially costly deteriorating performance going forward.
Another decision made in the elevator industry is to practice a “run to failure” versus preventative maintenance approach. When applied to the UC3 valve scenario we come across a 37 year old valve still in use today because it hasn’t failed. Based on the age and its use the valve is most likely not operating as well as it could and should be replaced. Sadly the option of rebuilding or repair often becomes the “cheaper” route taken. The Maxton UC3 has not been manufactured since 1977 and was discontinued in 1988 with no OEM parts manufactured to support the product since. Therefore, approved OEM parts are not available to properly rebuild or repair the UC3 valves. So, anyone trying to rebuild or repair the UC3 is doing so without Maxton OEM instruction or approval and with suspect non-OEM parts. That being said, you have to ask, where does the “cheaper” option leave me, my company and my customer if things go wrong?
