Stopcocks, valve and keys - burette valve with PTFE needle

Needle valves, sometimes referred to as plunger valves, are regulating valves and enable to finely control and regulate flow and pressure.

We offer many sizes and shapes.

For production we use PTFE and Simax borosilicate glass tubes. We allways check glass quality, dimensions and optical clarity.  The valves are tested to be leaking free.
