Pressure controllers

Our range of Alicat pressure controllers is available with single or dual valves. They can be used in standard, vacuum, differential, closed loop and closed volume pressure applications.

The Alicat PC series range of pressure controllers have single control valves with different valve options dependent on your application.

The Alicat PCD series are dual valved pressure controllers. All pressure controllers are available with a remote pressure sense port should your process require it.

The PC and PCD series pressure controllers from Alicat are also available for more aggressive applications featuring all 316 stainless steel wetted parts and FFKM seal options.

Every single pressure controller from Alicat features an analogue output signal as well as RS232 data communications.

Frequently asked questions

A pressure controller is an electronic device that maintains a constant pressure by actively regulating the pressure of a gas or liquid within a system. It adjusts valves based on feedback from pressure sensors to ensure stable control.
Electronic pressure controllers compare the measured system pressure to a setpoint. The controller then modulates internal valves to increase or decrease pressure, ensuring the target pressure is consistently maintained.
PCT supplies both single- and dual-valve pressure controllers suitable for gases and liquids. These include closed-loop controllers for both upstream and downstream pressure regulation.
Absolutely. The controllers are designed for integration into SCADA, PLC, and custom OEM systems, with flexible communication and control options.
Yes. We offer pressure controllers made with chemically resistant materials like stainless steel, PTFE, FFKM and Hastelloy for handling aggressive or high-purity fluids.
Yes. PCT provides pressure controllers capable of handling both positive pressure and vacuum conditions, including devices for fine control in low-pressure ranges.
Our pressure controllers support a wide range of digital and analogue outputs, including RS232, RS485, Modbus, EtherCAT, PROFINET, and analogue signals like 0–5 VDC or 4–20 mA.
They're widely used in semiconductor manufacturing, analytical instrumentation, gas mixing, medical devices, aerospace testing, and chemical dosing applications.
Response time varies by model and configuration, but many of our electronic pressure controllers offer fast response in the range of milliseconds for tight, dynamic control.
Yes. Our technical team offers expert guidance to help you choose the right controller for your pressure range, fluid type, and control application. We also provide integration and calibration support.
