Sample Valves

The sample valve is usually mounted above the racking valve on the tank and it screws into a coupling welded to the tank. You can also order a 1-1/2” Triclamp® ferrule to be welded on instead. The sample valves come in two styles, lockable and standard.

The standard valve has a threaded plunger which when unscrewed releases wine through the port. It has two O-rings and is easy to strip and clean and inspect the O-rings for damage. A little food grade Silicone on the threads helps with ease of operation.

The lockable sample valve has a very similar operation. The knurled knob has holes and matches a backing plate. You can put a padlock through the knob and plate to secure the valve. This is often used on tanks outside the winery building and on spirit tanks.
