I cannot find the activator MSDV3F anywhere will this do instead?

Hi MSDV3F is a 3 way valve with 3pin electrical connection. MPE222 is 2 way actuator head only. with 4 wires Regards David

mine says 6w 36 MA will this wirk?

Mine said 6w 36ma even though it's a single, one in,one out. Replaced it with this one with fingers crossed, and work perfect now got heating again, hope this helps anyone else.

My honeywell mid position valve has 5 wires but the myson mid position has 4 will it still work? there is no white wire?

Are you sure you need this model as my actuator head was for a 2 port not a 3 port mid position valve. Please double check what head you need ie. 2 or 3. Hope this helps.

What is the life of a myson 222 actuator

That’s a how long is a piece of string question. The one I replaced when I bought this one lasted about 15 years
