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 valves control liquids and gases in industrial applications.
