ARX Series Compact Pressure Regulator

Brand: SOLH by Richge Technology (睿其格科技)

Product Positioning

     ARX series, dominated by ARX20 model, is a mini piston relief regulator supporting maximum 2.0MPa inlet pressure. Targeted at compact equipment with high-pressure air supply and small-flow precise adjustment scenarios, it integrates tiny dimension, zero continuous air bleed, large flow capacity and multi-port flexible piping layout.

Structure & Working Principle

     --Direct-acting piston structure with built-in relief function

     --Max inlet working pressure reaches 2.0MPa, exceeding 1.0MPa limit of ordinary AR regulators

     --Zero steady air consumption without permanent air bleed

     --One supply inlet matched with three independent output ports for diversified piping

     --Miniature overall dimension: 35mm width, 80mm length, net weight only 110g

Core Key Features

1. High Inlet Pressure Resistance (Core Advantage)

     Max working pressure: 2.0MPa; proof pressure: 3.0MPa. Two adjustable pressure versions are available: ARX20 for 0.05–0.85MPa wide range, ARX21 for low-pressure 0.05–0.30MPa precise control.

2. Ultra-Compact & Lightweight Body

    Overall size 35mm × 80mm, merely 110g weight, perfectly embedded into narrow installation spaces and integrated automation equipment.

3. Zero Air Loss & Elevated Flow Output

     Zero continuous air consumption for outstanding energy-saving performance. Its flow capacity doubles that of regular regulators in the same size class.

4. Triple Outlet Ports for Flexible Layout

     Three output ports support multi-channel gas distribution, pressure gauge installation or blank plug closure. The Rc1/8 gauge port is reserved, and optional mounting bracket enables multi-directional installation.

5. Stable & Maintenance-Free Operation

     Applicable temperature range: -5℃ ~ +60℃. Automatic relief releases excess pressure for circuit protection. Lubrication-free internal structure cuts daily maintenance workload.
