The Itron B531 is ideal for light to medium commercial service where high-degrees of safety or overpressure protection are required, such as schools and hospitals.

The Itron B531 is a spring-loaded regulator equipped with a valve body that is effectively two regulators in parallel. This design allows for nearly double the capacity that can be achieved with a single 6″ diaphragm regulator. The B531 design is symmetric about that downstream piping so all parts are identical in both diaphragm cases.
