Industrial Regulators

BACK PRESSURE REGULATORS

MODEL DA-5 The DA5 is an excellent back pressure regulator for all fluid types. The regulator features a high flow design with standard balanced trim. The balanced trim allows rangeability up to 500:1; allowing for varying flows with very little change in set pressure. Due to the high capacities these regulators provide, it is now possible to install regulators where control valves once were needed. This allows additional savings since controllers, positioners, and auxiliary air are not needed. The Model DA8 is similar to this regulator except it provides positive bias differential construction.

MODEL DA-6 The DA6 is a pressure loaded back pressure regulator for all fluid types. Much like the DA5, the ability to allow varying flows with little change in set pressure makes this an ideal regulator for high accuracy applications. When the precision of automated controls cannot be sacrificed, the dome-loaded series is ideal. The ability to load the regulator with a wide variety of pilots, airsets, and I/P transducers allows for accuracy and automation in a small inexpensive package.

MODEL DA-8 The DA8 is a positive bias differential back pressure regulator for all fluid types. Much like the DA5, the ability to allow varying flows with little change in set pressure makes this an ideal regulator for high accuracy applications.
