Pressure Controllers for Industrial Gas and Vacuum Control
Our range of pressure controllers is designed for users who need responsive, repeatable control of pressure in compact systems, laboratory OEM assemblies, and industrial process environments.
- Digital pressure control: Select compact digital instruments for precise setpoint management, live display visibility, and easier operation in regulated gas and vacuum applications.
- Vacuum and low-pressure capability: The category includes solutions suited to vacuum control, Pirani sensing, diaphragm-type sensing, and low-pressure system regulation for test benches and analytical setups.
- Integration into technical systems: Pressure controllers in this range are well suited to OEM equipment, laboratory skids, and industrial control layouts where stable pressure, compact footprint, and straightforward connection points matter.
How to Choose the Right Pressure Controllers
Selecting the right pressure controllers for your facility depends on the control method, pressure range, and how the instrument will be integrated into the wider system.
- Pressure range and control mode: Check whether you need positive pressure, vacuum pressure, or low-pressure control, and confirm whether a single-valve or dual-valve configuration is the better fit for the process.
- Sensor and connection type: Review whether your application requires Pirani, diaphragm, or thermocouple-based sensing, along with suitable process connections such as NPT or NW formats.
- System use case: Consider whether the controller will support laboratory OEM builds, leak testing, vacuum handling, or industrial instrumentation where fast response and repeatable regulation are important.
Related Equipment for Complete Pressure Control Setups
Pressure control rarely operates in isolation. Buyers often review adjacent categories to build a complete measurement and control package for commissioning, testing, or production support.
- Pressure sensors: Add compatible sensing hardware where upstream or downstream pressure measurement is needed for monitoring, calibration, or feedback control.
- Laboratory vacuum pumps: Pair controllers with suitable vacuum generation equipment when building regulated vacuum lines, analytical systems, or bench-scale process assemblies.

Frequently Asked Questions
What are pressure controllers used for in industrial systems?
Pressure controllers are used to regulate and maintain a defined pressure setpoint in gas, vacuum, or low-pressure systems. They are commonly used in OEM equipment, leak testing, process control, and laboratory instrumentation.
What is the difference between a single-valve and dual-valve pressure controller?
A single-valve controller is typically suited to flowing systems where one control path is sufficient. A dual-valve controller is often preferred where faster correction or tighter control is needed in closed or changing-volume applications.
Can pressure controllers be used for vacuum applications?
Yes. Many pressure controllers are configured for vacuum and low-pressure operation, making them suitable for vacuum research, analytical equipment, and controlled evacuation processes.
