    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.
    Kyle - how does Viton stand up??

    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?

    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!
