Panel-Mount Vacuum-Regulating Valves for Air


Vacuum Gauge Not Included	Vacuum Gauge Included

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.

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.

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.
