Alicat PCR - Single Valve Pressure Controller

  • Available for gauge and absolute pressures up to 3000 PSI / 207 Bar
  • Differential pressures up to 100 PSI / 7 Bar
  • 50-100 ms speed of response stills upstream fluctuations
  • For higher flow applications
  • Up to ±0.125% of full scale accuracy

Fast-responding pressure, vacuum or differential control for high flow processes.

Alicat PCR series of pressure controller maintain precise control in your absolute, gauge of differential pressure applications. Additionally they can be configured for either a vacuum pressure or back pressure control.

PCR series maintain pressure stability and accuracy at high flow rates up to 5000 SLPM. Alicat is the world’s only manufacturer of near-frictionless Rolamite valves for precise control of high-rate fluid flows. Proprietary orifice patterns enable us to customize a Rolamite to satisfy your application and performance requirements.

The PCR series pressure controller is repeatable and accurate with calibrations up to ±0.125% of full scale accuracy. Every PCR series controller has a 3/4” NPT female connection and are typically suited to higher flow applications where the flow rates exceed 20 LPM.

Every device has a 200:1 turndown ratio with many standard pressure ranges available, standard pressure units include PSIA, PSIG, mmHG, inHG, inH2O, mBar, Atm, Torr and kPa.

The digital pressure controller features a local LCD screen and push button user interface to change process variables. A colour TFT display is also an option to. RS-232 communications are standard as well as an analogue output signal such as 0-5 Vdc. Modbus-RTU, available over RS-232 or RS-485 and PROFIBUS protocols are also available.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.
