Swagelok SS-42GS4 40G Series One-Piece Ball Valve, 1/4 in.

Reach for the SS-42GS4 when you want fast, positive on-off shutoff in a compact 316 stainless steel body. This one-piece 40G Series valve drops straight into your 1/4 in. instrument lines with genuine Swagelok tube-fitting ends, so you get a leak-tight seal you can trust the first time. You gain a smooth quarter-turn lever, a 0.6 Cv flow path through a 0.125 in. orifice, and a modified PTFE UHMWPE packing that stands up to hard cycling. Rate it to 2500 psig at 100°F and run it from -65 to 300°F without second-guessing your ratings. It even ships low-emissions certified to Swagelok's WS-22 standard, so you keep fugitive emissions in check on tight process loops. Put it on sample lines, analyzer racks, and instrument air, and count on clean shutoff every time you close it. Need a different orifice, handle, or cleaning spec for your application? Call Collins-Oliver and we will match the exact 40G Series build you need.
