Duncan Co can provide Sanitary Ball Valves for Breweries and Distilleries

sanitary valves for breweries and distilleries

Brewers and distillers obsess over cleanliness, and for good reason.  Sediment trapped in the tanks, pipes or valves can be a potential source for contamination.  Because of this, caustic cleaning is carried out regularly, usually followed by a steam cleaning for sterilization.

That is why stainless steel sanitary valves are your best choice, they can withstand the high temperatures and chemical attack and can be manufactured with smooth surfaces that leave no microbes to hide.

Valves used in brewing are either threaded or use the tri-clover clamp design, which is preferred because it’s difficult to get sediment out of threads.

We can help you control your flow with manual or actuated valves.  Contact us today for more information on how we can help you!
