B531 Commercial Regulator

The 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.

Field interchangeable brass orifice and adjustment spring
54 CUIN of combined diaphragm area
Twin Spring-loaded internal relief
Wide Range of NPT valve body sizes including NPT and Flanged connections
Controlled breather orifice size eliminates pulsation and provides normal actuation at low flows
No special adjustment tools needed
