Alicat Scientific PC, PCR Specifications

Technical Data for PC, PC3, PCR, and PCR3 Single Valve Pressure Controllers

Alicat PC-Series pressure controllers allow the precise control of absolute,gauge or di󰀨erential pressure.

These units can be congured for vacuum pressure or backpressure control.
PCR-Series pressure controllers are best for ows greater than 20 lpm.

www.alicat.com/pressure

PC3 and PCR3-Series pressure controllers are tted with an external pressure port for
sensing and controlling pressures at a remote point in the system.
