## Summary description

UN RPN4 is a low plate-type pressure regulator designed for controlling fluid or gas pressure in installations with an operating range of 0–40 bar. Supplied as a single unit, this compact regulator mounts on a plate or panel and provides stable pressure regulation for industrial or commercial systems, valves, and pipelines requiring accurate downstream pressure control.

## Long description

UN RPN4 is a low plate-type pressure regulator designed to deliver stable downstream pressure control for fluids or gases within an operating range of 0–40 bar. Supplied as a single unit, the compact regulator is intended for mounting on a plate or panel and integrates with industrial and commercial installations where precise pressure maintenance is required. The design emphasizes compactness and reliable mechanical regulation suitable for valves, pipelines and control systems that need predictable setpoint behaviour.
Advantages
The RPN4 provides accurate pressure control across a wide operating range up to 40 bar while occupying minimal installation space thanks to its low plate-mounted format. Its single-unit configuration simplifies installation and replacement, and the mechanical regulation mechanism offers repeatable performance with minimal adjustment drift. The compact construction supports straightforward integration into panels and assemblies, reducing the need for additional brackets or housings.
Suitable for
Panel- or plate-mounted pressure control in industrial fluid systems
Pressure regulation of gas supply lines and pneumatic installations
Downstream pressure control for valves and actuators
Pipelines and manifolds requiring compact regulators
Key specifications
Operating pressure range: 0–40 bar
Mounting type: low plate/panel mount
Configuration: single-unit regulator
Application medium: fluids and gases
Intended use: downstream pressure control
How to use
Install the regulator on a suitable plate or panel following the enclosure and mounting dimensions of the installation. Connect the upstream supply and downstream lines in accordance with the system flow direction, ensuring compatible fittings and thread sealing where required. Adjust the regulator setpoint using the manufacturer’s adjustment mechanism while monitoring downstream pressure with a calibrated gauge. Verify system tightness and perform functional checks at several flow rates to confirm stable regulation across the 0–40 bar range.
Usage recommendations
Use appropriate filtration upstream to prevent particulates from entering the regulator and causing wear or instability. Select compatible materials and seals for the process medium, and follow periodic inspection intervals to check for leaks, seal condition and accurate setpoint retention. If the installation requires electrical monitoring or remote control, combine the RPN4 with external sensors or transmitters designed for panel integration.
