The PGR-1 from Cashco, Inc., is a high accuracy, pressure loaded, pilot-operated, pressure-reducing gas regulator. The PGR-1 is already 
available in 1, 1 1/2, 2, 3 and 4-inch body sizes, with more to follow, and can be ordered in four basic materials with multiple trim material combinations. The PGR-1 design includes an internal pressure balancing piston-cylinder providing high flow capacity allowing customers to use a smaller body size than if they were using another regulator in the same application. This regulator can also be configured for operating temperatures ranging from -70° to +250°F and outlet pressure set points between 2 inch water column and 200 psig depending upon body/cover and dome/diaphragm material combinations.
