    motorized ball valve recommendations

    We are using a self-made keg washer and seem to be running through the motorized ball valves every few months on the acid side. This is the most recent valve we used https://www.amazon.com/BACOENG-Stain...tainless+steel

    Does anybody have a recommenation for a valve that won't be eaten up by the acid cycle?

    Thanks!

    I was looking at this brand for a few diy items. How is the valve being worn down? I would think it's the internal seals. Can't you just rebuild it with new seals?

    The model of valve you linked has EPDM and PTFE in the seal. EPDM doesn't resist acids very well, so I imagine that is the problem.

    You want a valve with PTFE (Teflon) 'wetted' parts (seals). It looks like this valve can't be rebuilt, so try to find a replacement that can. With a lot of cycles and temperature changes, even PTFE seals will wear out eventually.

    I've had good experience with Apollo, Nibco, PBM, and Flowserve valves, but I think any valve that has the right seals and a watertight actuator will work well.
