Model PGR-2

Description

Model PGR-2 is a pressure loaded diaphragm-type, reducing regulator. 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-2 regulator is applied primarily in clean natural gaseous service and fuel gas - sweet or sour. 

Inlet Design Pressure

• 10–600 psig (0.68 – 41.3 Barg)

Outlet Pressure

• 0.5" WC – 200 psig (13.8 Barg)

Line Sizes

• 3/8" (DN10)
• 1/2" (DN15)
• 3/4" (DN20)
• 1" (DN25)

End Connections

• Female NPT 
• ASME Flanged:
  • - 150#, 300#

Material Combinations: Body / Cover Dome

• DI/CS
• CS/CS
• SST/CS
• SST/SST

DI = Ductile Iron
CS = Carbon Steel
SST = Stainless Steel

Features

• Versatile: Three basic materials with multiple trim material combinations to select from. 
• Tight Shutoff: Composition seat materials BC, FKM, V-TFE or NBR. 
• Capacity: Handles mid-range flow rates on a line size basis. 
• Droop: Highly accurate outlet pressure control, due to absence of range spring in main valve design, provides almost zero “droop effect”.
• Trim Design: FTC - Incorporates the typical reducing regulator internal design. Internals can be easily removed.
• Incorporated Cylinder: Plug is guided through its travel by the cylinder, which also serves to block harmful debris from entry to the seating surfaces.
• Failure Position: Fails close on loss of loading pressure. Fails open on loss of P₁ or P₂ pressures with loading pressure yet applied.
• Remote Venting: Spring chambers on the pilot and the stabilizer include FNPT connections for remote venting of hazardous or explosive gaseous service.
