Leaking zone valve

 I have a leaking zone valve when the valve is open. 20 years old Honeywell vc8715. I need a replacement cartridge for this valve. I'm having trouble finding any information on what will work now in this valve. Do I need to replace it with a new valve?

Thanks

    If it is a standard residential honeywell motorized valve the guts can be replaced. If it is the older design you need a retrofit kit that changes it to the type where the actuator can be removed without opening the system.

    I think that is the actuator number. Is there a number on the brass valve body?

    I will have to check on the valve body when I return next week but I don't think I saw any more numbers on the body. This valve is about 22 years old. I have a tool ordered to take the guts out. When I do I can post a picture of the valve body and the stem assembly. Thanks

    With the age of the valve I would replace the whole thing.
