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. The valves are sold through a network of manufacturers' representatives.
Cashco also manufactures and warehouses fuel burning parts for the Riley Stoker Corporation. The parts for which Cashco is responsible go into machinery that pulverizes coal in preparation for burning. Cashco does not market or engineer fuel burning parts.
