Take liquid samples in sanitary environments—these sampling valves have a hygienic design, so they’re commonly used in breweries and wineries. With a body made of 316 stainless steel and a PTFE plastic seat, they resist the high temperatures and harsh chemicals of clean-in-place (CIP) processes. These valves have an extremely smooth surface, leaving no space for bacteria to grow. Quick-clamp connections, also known as tri-clamp fittings, are easily taken apart for regular cleaning. These valves are self-draining, so previous samples and cleaning chemicals won’t contaminate future samples. Both the seat and the silicone O-ring comply with FDA standards for direct contact with food and beverage.

To take samples, turn the thumb screw to open valves. Hang a bucket for sample collection from the bucket groove. Valves also have a leak detection port that will release a small amount of liquid to let you know when it’s time to replace all the valve seals.

Valves with a bent spout have a tab for connecting carbon dioxide testing devices. They’re often used for carbonated beverages. They shouldn’t be used with liquids that have solids in them, such as the grape skins or seeds in wine, as those can get caught in the outlet.
