Models 8311HP and 8311LP are reliable, high-capacity regulators ideal for remote installations when air and electric controls are not available. Dual-port construction makes these Cashco's highest-capacity back pressure regulators. Both models share the same basic design, differing only in diaphragm size.
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.
