Motorized Valve for Zone Control

I have a Honeywell v8043f1036 motorized valve on my hot water heating system. It is a three zone system . The one valve make a humming sound like it is still tring to close . It stops if I lightly tap it with my finger. Is this motorize valve failing? Or does the mechanizm not some clean or lube? thanks

when the thermostat calls it energizes the motor in the valve head. this turns and opens the valve and at the same time it moves a lever that energizes the end switch for starting the heater. The motor stays energized the whole time the valve is opened. Once the temp is reached the power to the motor from the thermostat drops out and a spring pulls the valve closed.

If the motor is humming it could be on it's way out. you can buy and replace just the motor by removing one screw without having to replace the whole head.
How hot does it get

cheap and easy to do

Valve motor

Some plumbing supply houses carry them but not many, at least in my area. For an online source, you might want to try patriot-supply.com.

Check eBay. There are often new heads and motors offered over there, at a fraction of what you will pay not being in the trades.
