In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I have older Erie zone valves. The issue is that the gears on the motor have stripped out the plastic gears on the valve lever (the lever with the spring tension on it). My question is - when the motor is activated, is it supposed to be de-activated (electrically) at some point during the zone valve operation? The motor keeps on running - which has put too much stress on the gears on the lever that opens the valve (in the open position which is the peak of tension by the spring) - and it has stripped out a gear tooth in the open position - thus causing a loud clicking noise during the zone operation. OR - is this just a case a fatigued plastic parts?
These Erie zone valves are 20 years old.
