B531 Commercial Regulator
Brand: ItronThe Series 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.
Features- Interchangeable brass orifice
- Combined 54 in² of diaphragm area
- Twin Spring-loaded internal relief valve assemblies
- Field interchangeable adjustment springs
- No special adjustment tools required
- Controlled size breather orifice eliminates pulsation and provides normal actuation at low flows
- Wide range of valve body sizes
Benefits
- Eliminates parallel regulator piping installations
- Light weight
- Fast response protects equipment from shock damage
- Field inspection of the internal monitor and internal relief valves without customer shut-off or by-pass
- Unmatched overpressure protectin with internal monitor plus internal relief options
