Looking for a replacement actuator

I have an older Stadler Viega mixing station. It has a honeywell M7410C1015-OV . It appears to be toast. I say this because I removed it from the valve and powered it up and the piston did not move. So I am looking for a replacement, I understand these are out of production. A replacement might be a Residio MSLF-B030-150. Google doesn't find any in the states. So here I am to see if anyone knows where I can get one of these guys or a different replacement.

Thanks so much

    did you wait long enough for it to heat up? those heat motor actuators take something like tens of seconds to a couple minutes for the wax to heat and move the actuator

    Many Honeywell M7410C1015 on eBay.com, most in China. Not sure what the -OV suffix means.

    Seems at least the stroke of the MSLF-B030-150 is different 8mm vs. 6.5mm for the M7410C1015.

    hi Mattmia2

    I can hear a motor in it running when I put power to it, I thought it was motorized.

    Hi 109A_5

    I saw those on ebay, they are crazy expensive, at least to me. I'll keep looking. Maybe I bought a unicorn for a mixing station, 20 + years ago.

    maybe it is motorized but usually those use a heat motor.

    This one uses a motor that drives the spindle. I'll try looking harder for the residio part

    I’ve used the Rehau actuators several times to replace those motorized Honeywells on the old Viegas.

    Thanks Ironman

    Do you remember what models? I am converned with the connection to the injection station, movement distance and power required. I think the connecction is 1 inch and the movement is 1/4" Is Rehau a US company? Not that it matters much just the shipping time and cost.

    Thanks!

    As far as I know, Rehau only offers one actuator.

    RE Michel is the largest Rehau distributor that I know of.

    i found a replacement / alternative Honeywell actuator on Ebay. And it didn't cost my first born either.

    Thanks all for your help!
