ARM5 Series Ultra-Compact Pressure Regulator (ARM5S)

Brand: SOLH by Richge Technology

Product Positioning

     ARM5 single regulator model ARM5S is a 14mm ultra-narrow direct-acting piston pressure regulator with built-in standard reverse flow function. It features tiny dimensions, optional single independent installation or manifold stacked assembly, integrated one-touch push-in connectors and high-precision pressure tuning. This mini regulator is customized for miniature pneumatic circuits with strict space limitation requirements.

Structure & Working Principle

     · Direct-acting piston construction; relief version as standard, non-relief version optional

     · Standard reverse flow design permits backflow from outlet port to inlet port

     · Integrated push-in fittings available in straight and elbow types for φ4, φ6, 5/32" and 1/4" tubing

     · Two mounting solutions: direct panel mounting and DIN rail mounting

     · Ultra-light body weighing merely 33 grams

Core Key Features

     1. 14mm Ultra-Compact Narrow HousingThe body width is only 14mm, with volume reduced to 1/7 of conventional AR20 standard regulators. It fits seamlessly inside embedded machinery, control panels and compact small jigs.

     2. High-Precision Adjustable PressureAdjustable pressure range covers 0.05–0.7 MPa. Standard relief model releases excess pressure automatically for stable output; optional non-relief model delivers superior pressure retention performance.

     3. Built-In Standard Reverse Flow FunctionThe internal channel opens automatically once outlet pressure exceeds inlet pressure. It can be directly installed downstream of solenoid valves to simplify overall air circuit layout.

     4. Flexible Connectors & Multiple Mounting WaysStraight and elbow fittings are interchangeable for inlet and outlet ports. The regulator supports direct fixing and DIN rail stacking, with an optional side-mounted pressure gauge rated at 0.8MPa.

     5. Corrosion Resistant & Long Service LifeCombined resin and aluminum alloy housing resists corrosion. The applicable ambient temperature ranges from -5℃ to +60℃. Lubrication-free operation ensures stable long-term cycling performance.
