Single Valve Pressure Controllers

Single valve pressure controller

Electronic Pressure Controllers / Electronic Pressure Regulators

Alicat Scientific PC-Series digital pressure controllers provide precise control of absolute or gauge pressure of process gases and liquids. For backpressure control, the PC Series is available with downstream valves and inverse valve control algorithms. Alicat Scientific PC-PSID Series digital differential pressure controllers maintain the pressure differential between two points in a process using separate dead-ended pressure sense ports. Alicat digital pressure controllers come with NIST-traceable calibration sheets.

Alicat PC series pressure controllers utilize the same valves used in Alicat’s mass flow controller line resulting in fast and accurate pressure control. With a fully functional digital display and a host of other standard features Alicat’s PC series line of pressure controllers are a feature rich solution for applications requiring precise pressure control.

Alicat PC series pressure controllers are:


Alicat’s PC series pressure controller is more precise than standard manual regulator pressure controller.


A variety of output options including 0-5V, 0-10V and 4-20mA and RS-232 allow users to tailor the PC series pressure controller to their application. Modular design allows PC series pressure control instruments to be configured for use in vacuum control applications as well as pressure control applications. PC instruments are available in ranges from 4″H20 PSIG through 100PSIG; 15PSIA through 100PSIA; 4″H20PSID through 150PSID.


With a 50ms response time, Alicat PC series pressure controllers are ideal for a variety of applications in which precise and stable pressure control are a requirement.

Cheap to operate

Alicat PC seris pressure controller require very low power to operate and when used properly require minimal maintenance.


Standard 302SS (optional 316S) flow body with aluminum case housing looks good and provides long service life.

Accurate and Repeatable

Accurate to +/-0.5% of FS and repeatable to +/-0.5% of full scale.

All Alicat PC series pressure controller calibrations are NIST traceable.
