ARJ310 Series Miniature Pressure Regulator (Relief Direct Operated)

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

Product Overview

     SOLH ARJ310 series is a direct-acting relief ultra-compact precision pressure regulator for narrow installation spaces and low-flow high-precision pressure control. Its overall dimensions and performance are fully interchangeable with SMC ARJ310 original regulators for direct equipment replacement.

Structure & Core Functions

     --Structure: Direct-acting piston type with built-in relief vent

     --Two-port layout (IN / OUT); excess pressure automatically exhausted through internal relief channel

     --Function: Steadily lower inlet air pressure to preset output value, suppress pressure fluctuation and offer overpressure protection

     --Integrated design with one-touch push-in outlet and dual optional inlet threads for flexible wiring

Technical Specifications

     --Working Medium: Clean & general industrial compressed air

     --Max Operating Pressure: 0.8 MPa

     --Proof Pressure: 1.2 MPa

     --Adjustable Pressure Range

     --Standard range: 0.2–0.7 MPa

     --Low-pressure version: 0.05–0.2 MPa

     --Ambient & Medium Temperature: -5℃ ~ +60℃ (no internal freezing)

     --Net Weight: Approx. 65g

     --Body Width: 18.5 mm, suitable for dense manifold stacking

     --Protection Grade: IP65

Port Configuration

Inlet Port (Two Selectable Styles)

     --M5×0.8 internal thread

     --Rc1/8 external thread

Outlet Port

     Rc1/8 female thread with integrated push-in connector, compatible with φ4/φ6 metric tubing, 5/32" & 1/4" imperial tubing

Gauge Port
