Description
The Norgas Controls and Metering B34SR-1 1/2 is a 1-1/2″ internal relief valve (IRV) gas regulator engineered for dependable downstream pressure regulation in commercial and industrial gas distribution systems. Featuring a 5/8″ x 3/4″ orifice and a factory-set 6–9″ W.C. spring range, this regulator delivers precise, consistent outlet pressure control to protect downstream appliances and equipment from over-pressurization.
Norgas Controls and Metering is a trusted name in gas metering and regulation, manufacturing products built to withstand the demands of commercial gas service. The B34SR series combines robust construction with an integrated internal relief function, providing an added layer of safety by venting excess pressure directly within the regulator body — eliminating the need for a separate external relief valve in many applications.
