Need a flanged AND side seal valve option for your application? Look no further than Model #154 and Model #191, which combine both features in one small 0.455″ length valve. These two options are easily inserted into 5/8” device. The external o-ring side seal keeps the valve in place, while also providing an extra barrier against leaks.
Typically used as pressure relief valves, Model #154 is designed as an inlet and Model #191 as an outlet. Both valves work with a wide variety of liquids and/or gasses, and they can produce five times more flow versus our Model #122 and #132 options. Model #154 and #191 are both in our Series 100 Specialty line of check / pressure relief valves. Available plastics include: Polypropylene, Nylon, Acrylic, PVDF, Polycarbonate, Ultem®, and ABS plastic body materials. O-ring options include Buna-N, EPDM, Viton®, Silicone, Fluoroslicone, and Aflas ®. Opening spring pressure ranges from 0.11 to 8 PSI.
