Arrow Pneumatics R354G Pneumatic Pressure Regulator

Arrow Pneumatics R354G is a 1/2" NPT pneumatic pressure regulator with gauge included, designed for high-flow, precise control in industrial air systems. It supports inlet pressures up to 250 psi and delivers an adjustable downstream pressure of 5–125 psi, with a rated flow of 100 SCFM. The compact aluminum body houses a micro-finished brass valve seat to minimize pressure creep and a reinforced diaphragm to maintain accuracy through frequent cycling; the overall width is about 2.69 inches, making it suitable for crowded panel installations. It features self-relieving action, a 3-position locking knob to secure adjustments, and a tamper-proof cap for added safety. The model is identified by part number R354G and is commonly used to regulate pressure for air tools and other pneumatic machinery on 1/2" piping systems that require reliable, maintainable regulation.
