Swagelok SS-1GS4 1G Series Toggle Valve, 1/4 in.

Grab the SS-1GS4 when your operators need instant, one-motion shutoff they can work by feel. This 1G Series toggle valve flips open or closed with a single flick of its nylon handle, so you cut and restore flow fast on bleed, vent, and calibration lines. The straight-pattern 316 stainless steel body threads into your 1/4 in. Swagelok tube-fitting ends and delivers a leak-tight seal you can count on. A soft-seat PTFE stem tip gives you positive, bubble-tight shutoff on low-pressure service, and the compact footprint tucks neatly onto crowded instrument panels. Rate it to 300 psig from -20 to 200°F and mount it on analyzer racks, pneumatic controls, and sample-conditioning systems where quick manual actuation matters. You get 0.2 Cv through a 0.125 in. orifice, plenty for fast venting and purging without fuss. The bright toggle handle shows open or closed status at a glance, so your team never guesses.
