Product Description

AR Series Pneumatic Pressure Regulator | SOLIH Modular Compressed Air Pressure Reducing Valve

Brand: SOLH by Richge Technology | Standard Modular Air Source Pressure Control Unit

1. Product Overview

SOLIH AR‑series is a standard pneumatic air source pressure regulator designed for pressure reduction and stabilization of compressed air. It can be modularly combined with AF air filter and AL lubricator to build AC two‑unit or three‑unit FRL assemblies. Widely deployed for air source pressure control on automation equipment, machine tools and production assembly lines.
