Descrizione del prodotto<\/h2>\n

A sanitary diverter valve<\/strong> built as a 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 L-port<\/strong> to divert flow between two destinations, or a T-port<\/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 line carrying food, beverage or process chemicals, that trapped product is 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 \u201cfood versus water\u201d \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 a sugar syrup does. A hot wash cycle above 80 \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

Every product-contact surface \u2014 ball, seats, body bore \u2014 can be reached by hand, cleaned and inspected before the valve goes back on the line. Spare seats are stocked, so a seat that has done its hours gets replaced rather than nursed.<\/p>\n
