    About Pressure-Regulating Valves
    industrial info icon

    Find a regulator that’s compatible with your gas, matches the CGA number on your tank, and has twice the operating pressure of your application’s normal range.

    Panel-Mount Back-Pressure-Regulating Valves for Air and Inert Gas

    Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel. Often used in systems running on air compressors, they're installed after pressure-sensitive equipment to obstruct flow and maintain a consistent operating pressure. If the system pressure exceeds the set pressure, they exhaust through the outlet. Adjust the set pressure within the range.

    For easy panel mounting in your water system, these valves have threads below the adjustment knob and come with a panel-mount nut. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Body is polysulfone, which is lightweight and corrosion resistant.

    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.
