Whose manifold is this , need to replace actuators

Rich_49

Can anyone assist in identifying whose ( manufacturer) manifold this is ? Actuators are bad , they are obsolete and trying to not replace manifolds also to keep costs down . No luck researching this myself so far .

those valve heads are still available

Is it RTI of Long Island, Dave H of Taco was part of that company.
Wirsbo, Honeywell and Sparco used that actuator, I think they were all the same.

Any idea where they are available ? Residio Honeywell discontinued them in March of 20' . I have not seen any of them from other manufacturers for quite some time .

I’ve used Rehau actuators to replace those and they  worked fine.

My Caleffi rep (who used to do Rehau) says theirs will work.
