    Extended-Life Vacuum-Regulating Valves for Air and Inert Gas

    Image of Product. Front orientation. Vacuum-Regulating Valves. Extended-Life Vacuum-Regulating Valves for Air and Inert Gas.
    For a longer service life than brass vacuum-regulating valves, these are made of bronze for strength and durability. They throttle a high vacuum source to maintain a lower vacuum level in your system. Turning the adjustment screw will adjust the vacuum setting.

    Plastic Panel-Mount Vacuum-Regulating Valves for Air and Inert Gas

    A lighter and more corrosion-resistant alternative to metal valves. All valves throttle a high vacuum source to maintain a lower vacuum level in your system. Adjust the outlet vacuum level within the range. Threads below the adjustment knob and an included panel-mount nut let you add these valves to your instrument panel. All are constant-bleed style, so they continually release small amounts of process gas to improve accuracy and repeatability.
