  • Looking to replace solenoids

    Howdy all,
    We are looking to replace our solenoids as several have finally given up the ghost. What brands/styles have proven to be reliable workhorses for your operation? We are cooling five, ten barrel FV’s (two zones) and five brites (one zone). The piping is 3/4”.
    Prost!

    Angle seat valves

    Pneumatic Angle seat valves with solenoid pilots are bulletproof, inexpensive, and reliable. Wouldn't use anything else.

      Howdy Phillip,
      Do you have a source for these?
      Prost!

        Not where you are!

        I've only purchased these outside the US. The last few times from Rotex. Sure you can find something of equal quality. Beware of dirt cheap crap, however.

          Id go with actuated ball valves instead. George Fisher sells some for their abs pipe but they also have adapters. Grainger/Mcmaster also

            Asco Red Hats are still working fine for us. For our larger fermenters, we use pneumatic poppet valves for the better flow, but the solenoids work fine for our 35-50 bbl ferms.

            You do need to be careful to keep small debris out of you system if using any piloted valves. Teflon thread tape has been our biggest source of problems. A piloted solenoid valve will stick in the open state if the tiniest bit of crud gets stuck in it.

              Thanks Tim,
              We’ve been using red hats as well. So long in fact, the label information has completed worn off. What model Red Hat are you using?
              Prost!

                I know this may fall into the "dirt cheap crap" catagory and for 10 or even 5bbl tanks id go with something better for piece of mind.
                That said, the risks are minimal for our nano 3bbl batch size compared to what some are using them for but For what its worth Ive been using generic valves like these off ebay for over a year and have yet to have any issues.. When building the system they were more or less a temporary installation as the whole system was only meant to be used until our renovations were done and a larger setup put in. That said I have been impressed with the 100% reliability thus far.

                I'm not suggesting they are any better or worse than any other option as they are one of the only type Ive ever used, im just sharing since it was asked and I have actual experience with them to share. These are only being used for the cooling side glycol mix.

                  We have a mis-mash of different models and sizes. Bad news is, without the data from the top plate, you can't order rebuild kits--that is all you have to go on. IIRC, there is nothing on the valve body to ID them.

                  I think I stock three different r'build kits here.

                    We just switched to Belimo ball valves with spring return. Started with solenoids, but maintenance became a nightmare. Our electrical system is protected by GFCI, so temperature related corrosion became a problem. The Belimo ball valves have all sealed connections. If you are running a 24 vac system, the Belimos' will fit perfectly to your tstats. Had our solenoids come with better connections, our experiences might have been different, but having additional issues with teflon residue clinched it for us.

                      Dave,

                      I understand the dislike of Asco Red Hats, but we have really only had problems with them on new installations, always teflon tape or solder getting stuck on the sealing surface and having the valve stick open. The ones I like are the zero-differential ones - the design is more forgiving of little bits of trash. I get them from Grainger, about $350 for a 3/4" one.
