    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.

    Regulate vacuum levels from your instrument panel with these valves that have threads below the adjustment handle and a panel-mount nut. They throttle a high vacuum source to maintain a lower vacuum level in your system. Adjust the outlet vacuum level within the range. Valves are constant-bleed style, so they continually release small amounts of process gas to improve accuracy and repeatability.
    Vacuum Gauge Included—Valve with gauge comes with a vacuum gauge for monitoring your vacuum level.

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

    Image of Product. Front orientation. Vacuum-Regulating Valves. 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.

    High-Accuracy Panel-Mount Vacuum-Regulating Valves for Air and Inert Gas

    Image of Product. Front orientation. Vacuum-Regulating Valves. High-Accuracy Panel-Mount Vacuum-Regulating Valves for Air and Inert Gas.
    For precise control over your vacuum level, these valves have ±0.1% accuracy. They throttle a high vacuum source to maintain a lower vacuum level in your system. Adjust the outlet vacuum level within the range. Valves have threads below the adjustment knob and come with a panel-mount nut. All have a gauge port. They are constant-bleed style, so they continually release small amounts of process gas to improve accuracy and repeatability.
