Model BGR-1

The BGR-1 is high performance pilot operated back pressure regulator intended for applications where upstream pressure control is critical for a broad range of flow requirements. The BGR-1 was designed for use with low back pressures up to 15 psi (1 Bar) and requires an auxillary pressure supply to operate. See BGR-2 for back pressures above 15 psi.

DI = Ductile iron
CS = Cast carbon steel
SST= Stainless Steel

NOTE: Remaining materials are stainless steel unless noted otherwise in Table 4.

Features

• Versatile: Specially designed for use on most industrial gasses with a broad temperature range. Multiple trim options are available for a wide variety of applications.
• Tight Shut Off: Meets ANSI/FCI 70-3 Class VI.
• Trim Design: A flow-to-open trim design allows for superior control at minimal flow conditions. The pressure balanced design also eliminates deviation due to supply pressure effects.
• Heavy-Duty Guiding: Two points of guiding allows for consistent sealing, reduced wear, and increased trim longevity.
• Failure Position: Loss of loading pressure to the cover dome will cause the valve
  to close.
• Remote Venting: This option allows the auxiliary supply pressure to be vented to
  atmosphere or to a remote location.
