Description
 
This is our new favorite style of sample valve for fermenters with 1.5" TC ports. This version uses an internal diaphragm that gets pressed against a seat for a simple, fast actuating open and close. We stock replacement rubber diaphragms which are easy to change out as necessary. As with most rubbers, you want to avoid soaking in PBW or Starsan for extended periods of time.

The other great feature of this unit is that it accepts a clamp-on dispensing coil. These coils have a lot of names; Sample Coil, Pig Tail, Proof Coil. Whatever the name, if your beer is carbonated in a Unitank or Brite Tank, you can't simply open up the sample valve or you'll have a cup (or face) full of foam. The Pig Tail Proof Sample Coil is available separately.


Don't forget that 1.5" TC flanges measure an actual 2". Material is 304 Stainless steel.

Reviewer: pinemarten from Augusta, ME United States  
I've used the screw type sample valves for years and didn't realize how terrible they were until I tried this.  This has smooth action all the way through. There is no big burst of beer surging out. You could drip it out if you wanted to. You can physically feel the stops on both full open and full closed eliminating guess work and even grabbing a pipe wrench to be sure you are closed with the other type.
