IR Series Precision Pneumatic Regulator

achieve exceptionally stable and accurate downstream pressure control. Engineered for high sensitivity (e.g., within 0.2% F.S.) and repeatability, these regulators are ideal for instrumentation, test equipment, and critical pneumatic circuits requiring fine pressure adjustment. Ensures consistent output even with fluctuating supply pressures.
