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