A sanitary 3-way ball valve in polished 316 stainless steel, driven by a rack-and-pinion pneumatic actuator (double acting or spring return). Tri-Clamp ends let you break the line without tools, and the ball is available with an \u0645\u0646\u0641\u0630 L<\/strong> to divert flow between two destinations, or a \u0645\u0646\u0641\u0630 T<\/strong> to mix two streams into one.<\/p>\n

The part that matters in hygienic service is what happens behind<\/em> the ball \u2014 see below.<\/p>\n

The Cavity Problem \u2014 and What a Fully Encapsulated Seat Does About It<\/h2>\n

In a standard ball valve there is a small gap between the ball and the body. When the valve closes, product sits in that gap. On a water line nobody cares. On a food, beverage or pharmaceutical line, that trapped product is where bacteria grow, where the last batch contaminates the next one, and where a sugar syrup crystallises solid.<\/p>\n

A fully encapsulated seat<\/strong> fills that space with PTFE. The ball touches nothing but the seat \u2014 there is no cavity, so there is nothing to trap product. This is what the industry means by a non-retention<\/em> ball valve.<\/p>\n

It is not free, though: filling the cavity with PTFE lowers the temperature ceiling. Choose with your process temperature in front of you.<\/p>\n

The judgement is not “food versus water” \u2014 it is whether your medium can be left sitting in a cavity, and how hot your line runs.<\/strong> A crystallising chemical needs a full seat as much as milk does. A hot CIP loop above 70 \u00b0C rules a full seat out. Tell us the medium and the temperature when you request a quote and we will confirm which seat you need.<\/p>\n

Cleaning: This Valve Comes Apart<\/h2>\n

The body bolts open. Undo the clamps, take the ball and the seats out, clean them, put it back \u2014 clean-out-of-place (COP)<\/strong>. You can see the parts you cleaned, which is more than can be said for a valve you can only flush from the outside.<\/p>\n

We do not claim this valve is suitable for automated clean-in-place (CIP) cycles. A ball valve has geometry that a CIP flow cannot reach; the honest answer is that it is designed to be opened.<\/p>\n
