PGR-1 Pilot Operated Pressure Reducing Regulator Pressure Loaded Diaphragm

PGR-1 is 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 gaseous service and fuel gas – sweet or sour.

Highest capacity in the industry. Allows smaller body sizes than competitors in majority of applications.

Highly accurate outlet pressure control, due to absence of range spring in main valve design, provides almost zero “droop effect”. FTO – pressure balanced trim results in unmatched sensitivity and stability.

Internals are cage-contained within easily removable quick change trim. Heavy-Duty guiding both top and bottom guided to maintain stability and increased diaphragm life.

Fails closed on loss of loading pressure. Fails open on loss of P1 or P2 pressures with loading pressure yet applied.

Spring Chambers on the pilot and the stabilizer include FNPT connection for remote venting of hazardous or explosive gaseous service.

Sizes: 1″ – 4″ (DN25 – 100)

Features:

Four basic materials with multiple trim material combinations to select from. Tight Shutoff with multiple composition materials provide Class IV and Class VI inboard leak age rates. Designed as a soft-seated valve.
