Precise compact pressure control

Staiger – Electronic pressure regulator

Precise compact pressure control

Ultra-Compact Design

Combines pressure regulation, sensing, and control electronics into one compact unit, reducing system complexity and space requirements, making it ideal for integration into space-constrained and highly integrated OEM applications.

High Precision & Stability

Closed-loop control with integrated sensing ensures accurate, repeatable pressure and vacuum regulation, delivering stable performance even in applications with very small internal volumes and demanding precision requirements.

Fast Response Time

Micro solenoid valve technology enables rapid pressure adjustments and dynamic control, ensuring fast response times and reliable performance in time-critical and highly dynamic processes.

Flexible Control Options

Available with on/off and proportional valve technology, offering flexible control strategies for both fast switching applications and continuous, highly precise pressure regulation tailored to specific system requirements.

Staiger – Electronic Pressure Regulator

The Staiger electronic pressure regulator is an ultra-compact solution that integrates pressure regulation, sensing, and control electronics into a single unit. By combining micro solenoid valves with an internal pressure sensor, it enables precise control of pressure and vacuum via electrical input signals. This allows continuous monitoring and dynamic adjustment of system pressure without the need for additional external sensors or interfaces.

Conventional pressure control systems typically require multiple components, such as separate sensors, valves, and controllers, which increase system complexity and the number of interfaces. These interfaces can introduce potential leakage points, slower response behavior, and higher integration effort. By integrating all essential functions into one compact device, the Staiger electronic pressure regulator reduces system complexity, improves reliability, and simplifies integration – particularly in space-constrained applications.

Staiger pressure regulator available in two variants

The Staiger electronic pressure regulator is available in two configurations, enabling optimal adaptation to different application requirements:

Pressure regulator with on/off valves

This variant uses high-speed switching of micro solenoid valves to control pressure. By rapidly opening and closing the valves, the system adjusts pressure dynamically, making it ideal for applications requiring fast response and robust control.

Pressure regulator with proportional valves

The proportional variant continuously adjusts the valve opening to regulate pressure smoothly and precisely. This enables highly stable control with fine resolution, making it suitable for applications where accuracy and minimal fluctuation are critical.

On/off regulators are best suited for dynamic processes with fast pressure changes, while proportional regulators are preferred for applications requiring continuous, highly precise pressure control.

Integrated Control, Sensor & Connectivity

The Staiger electronic pressure regulator is designed for straightforward integration and operation. It combines sensor, control electronics, and communication in a single unit, allowing precise pressure control with minimal external components.

Integrated Pressure Sensor

At the core of the system is a closed-loop control architecture. An integrated pressure sensor continuously measures the outlet pressure and provides real-time feedback to the control electronics.

The measured value is automatically compared with the defined setpoint, and the system adjusts itself accordingly. This enables stable, repeatable pressure and vacuum control without requiring additional external sensors or manual tuning.

Digital Input / Control Signal

The pressure regulator is controlled via a UART-based digital interface, allowing direct communication with a PC or higher-level control system.

For initial setup, the regulator is connected via the JST BM06B-GHS-TBT connector to an adapter board, which can be linked to a computer using USB-C. Using the provided software, users can:

Define and adjust pressure setpoints
Monitor system behavior in real time
Perform calibration and parameter tuning

If required, the regulator can also be controlled without the software by sending commands directly via the UART interface (baud rate: 115200), enabling integration into custom systems.

Electrical Connection

The electrical connection is realized through a compact JST BM06B-GHS-TBT connector, which combines:

Power supply
UART communication (Tx / Rx)
Control signals

The regulator requires an external power supply:

24 V DC for the proportional valve variant
12 V DC for the switching (on/off) valve variant

It is important to note that the USB connection is used only for communication—power must be supplied separately.
