ITRON RBE1800 Series (formerly Actaris) is a range of direct-operated, spring-loaded gas pressure regulators with an optional integrated safety shut-off device. Designed for medium-to-high pressure regulation, the series features a built-in balanced compensation system that ensures constant outlet pressure even during inlet pressure variations. Suitable for applications requiring rapid regulator response, such as LPG first-stage pressure regulation and industrial burners.
