CT-24 zone valve replacement

I have a ct-24 zone valve in my heating system, they heaters in them don't last very long (3 to 5 years). I was wondering if there is something out there that is motorized that would just clip on the same point as the old ones. If not I'm going to have to replace them in whole.

these are the ones I have now, thanks for any help that you may give.

    Might be time to start replacing them. A quality spring  return valve should go 15- 20 years
