Product Overview
The Itron RB1700 and RB1800 Pressure Regulators are compact, direct-acting, spring-loaded solutions engineered for safe and efficient gas pressure control in space-constrained environments. With a balanced valve design ensuring stable outlet pressure and an optional safety shut-off valve (SSV) for over-pressure and under-pressure protection, these regulators are perfect for industrial ovens, burners, and gas distribution systems. The RB1700 (¾" and 1") specializes in high-pressure reduction, such as LPG first-stage applications, while the RB1800 (¾" and 1½") supports large appliance regulation. A built-in creep relief valve and easy-reset bypass system enhance safety, making these regulators a reliable choice for natural gas, LPG, and other non-corrosive gas applications.
