The DA5 is an excellent back pressure regulator for all fluid types. This Cashco 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.
Cashco manufactures a proprietary line of self-contained regulators and control valves. The regulators are self-sufficient valves that control the flow based on line pressure at the regulator. By contrast, control valves control flow based on an external signal coming from a controller. Cashco regulators control liquids and gases in industrial applications.
