Alicat’s single-valve pressure controllers are designed to rapidly control the pressure of flowing processes.   They achieve new setpoints rapidly and stay put, even in the face of uneven feed pressure or changing temperatures.

Alicat’s PC series absolute or gauge pressure controllers contain pressure sensors that are referenced to vacuum (absolute) or to local barometric pressure (gauge).  The PC series differential pressure controllers maintain a constant pressure differential between their two measurement ports.

The PC series absolute and gauge transducers are available with a remote pressure sensor port (PC3) so you can control flow at a different point to ensure your pressure stays on target. Alicat’s PC3 series physically isolates the pressure sensor from the valve and flow path so that you can control pressure exactly where you need it.  This allows pressure control in areas where you cannot easily install a full pressure controller and reduces the effects of flow-induced pressure changes in high-flow applications.

As well, most instruments in the standard PC and PC3 series are available with an optional “S” configuration (PCS or PC3S) for use with liquids and corrosive gases.  In this configuration, the valve has been upgraded to 303 stainless steel, the sensor to 316L stainless steel, and the elastomers to FFKM.  If the corrosive gases you are working with require 316L stainless steel throughout the flow path, contact us about upgrading the valve (type PCA) and flow body.  Available for full-scale flow ranges of 20 slpm or less.

Alicat’s PC series of pressure controllers can be custom built with your choice of options.  Choose your communications protocol, display, process connections, elastomers, integrated potentiometer control, and calibration.  Need further customization?  Contact us and we’d be happy to help you build the instrument you need.

Each standard pressure controller comes with a NIST-traceable calibration certificate and an Alicat operating manual.  Power supply sold separately.
