PC–Absolute and Gauge Pressure Controllers
Fast-responding pressure, vacuum or backpressure control.
Order Directly from Alicat
Control the absolute pressure (referenced to vacuum) or gauge pressure (referenced to local barometric pressure) of gases or liquids in your process. Alicat’s PC series pressure controllers achieve new setpoints rapidly and stay put, even in the face of uneven feed pressure or changing temperatures. We’ll use your application parameters to customize your valve and PID tuning to ensure that your controller delivers fast and stable control.
- Fast & Accurate. Very fast valves and PID control algorithms hit pressure setpoints in milliseconds with NIST-traceable accuracy.
- Connected. Easy integration into your digital industrial network with EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
- Backpressure control option. Downstream valve positioning sets up your Alicat as a backpressure controller. This option works especially well with absolute pressure sensors to keep your process at a fixed pressure, regardless of changing weather.
Alicat’s PC series uses small proportional valves for control at lower flow rates and is suitable for use with non-corrosive gases.
Alicat’s PCP series offers the largest orifice in a small valve format and is suitable for use with non-corrosive gases.
Alicat’s PCH series pairs two small valves working side-by-side as one and is suitable for use with non-corrosive gases.
Alicat’s PCR series uses nearly frictionless Rolamite valves and a variety of orifice patterns for control at high flow rates and is suitable for use with non-corrosive gases.

Alicat’s PCS series uses small proportional valves for control at lower flow rates and is suitable for use with liquids and corrosive gases.
Alicat’s PCHS series is suitable for use with liquids and corrosive gases and pairs two valves working side-by-side as one to provide greater control at higher pressures.
Alicat’s PCRS series is suitable for use with liquids and corrosive gases and uses nearly frictionless Rolamite valves and a variety of orifice patterns for control at high flow rates.
