SMC 10-ARP20K-01BG-3 | 10-ARP K Series Clean Room Direct Operated Precision Regulator Body 20 1/8 NPT With Backflow Function Gauge

The SMC 10-ARP20K-01BG-3 is a clean room specification direct operated precision regulator from the 10-ARP K series, featuring an integrated backflow function for controlled downstream depressurization. The "K" suffix designates the backflow capability, which exhausts downstream air pressure reliably and quickly when the set pressure is lowered or supply is removed, preventing trapped pressure that could affect sensitive downstream equipment in clean room pneumatic circuits.

What additional features does the "BG" option provide? The "BG" specification indicates bracket mounting with an integrated round-type pressure gauge, providing visual pressure monitoring directly at the regulator without requiring a separate gauge or instrument connection. This simplifies installation and enables operators to verify pressure settings at a glance during routine clean room equipment checks, reducing the risk of undetected pressure deviations.

Configured in body size 20 with 1/8 inch NPT port ("01") and "-3" set pressure range, this precision regulator delivers setting sensitivity within 0.2% F.S. and repeatability within ±1% F.S. The combination of backflow function, integrated gauge, and clean series specification makes this variant a comprehensive solution for clean room pneumatic circuits where pressure control, monitoring, and safe depressurization are all required in a single modular unit.

The "10-" clean series ensures fluorine grease, clean workshop assembly, and anti-static double packaging. RoHS compliant and compatible with SMC's modular air preparation architecture for building complete clean room FRL systems.
