Model PGR-1 is a high accuracy, pressure loaded, pilot operated pressure reducing regulator. The flow to open design includes an internal pressure balancing piston-cylinder that provides high flow capacity. This internal trim design allows the same basic unit to cover a broad range of pressure settings.
Performance meets or exceed that of competitive pressure loaded or pilot-operated designs. The PGR-1 regulator is applied primarily in clean natural gaseous service and fuel gas - sweet or sour.
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.
