Factory Test
Every valve is tested with nitrogen at 1000psi(69bar) to maximum leak rate of 0.1 scc/min.
Causion
These valves do not have a stem seal. It is imperative to open the valve slowly and direct the vent tube away from persons operating or near the valve. Because of the absence of a stem seal, small amounts of fluid will go through the stem thread area when the valves are opened.
