Pressure Controllers for Closed Volumes

Alicat Pressure Controllers for Closed Volumes

Dual valve pressure controllers from Alicat eliminate the need for a bleed valve for pressure control in closed or dead-ended volumes. They are available with internal pressure sensors, or with remote sensors that can be plumbed to any point in your process. Each pressure controller is compatible with non-corrosive gases, and anti-corrosive models are available for use with corrosive gases or liquids.

Check out the model pages to learn more about our pressure controllers and the many custom build and performance options that are available.

Feel free to contact our applications engineers to discuss your application or ask any questions.

Alicat PCD-Series Dual Valve Pressure Controllers use two proportional valves to precisely control the absolute or gauge pressure of gases within closed or dead-ended volumes.

Alicat PCD3-Series Dual Valve Pressure Controllers use two proportional valves to precisely control the pressure of gases within dead-ended volumes, and physically isolate the pressure sensor from the valve and flow path so that you can control pressure exactly where you need it.
