sampling valve
(OP)
I am looking for a solution to sample oil (300ml), recirculating over a pump back into its own tank.
A simple tap can not be used as "bottom" tankvalve, as it is not reliable.
We do have experience with a bypass stream but is a messy operation (maybe not the right type of bypass (or operator..)).
Of course should the sample point be as clean as possible, so any voids need to be avoided.

Here's one.

Other types exist: One style pushes a piston into the line and opening a void behind the piston which then fills, then when the piston is retracted, the void drains into a sample cup.

The flowserve thing looks workable, some concern about the remaining dripping after sampling. The second, I recognised but I do not want to rely on the small seal for tightning....
Anybody with experience in using the flowserve type of sampler?
