BelGAS Distributors CP P5300 Back Pressure Regulator

DISTRIBUTORALATINDUSTRI.COM | BelGAS Distributors CP P5300 Back Pressure Regulator | BelGAS CP P5300 is a pilot-operated back pressure regulator designed to automatically maintain a controlled upstream pressure by regulating the flow of gas or process fluid downstream. It is engineered for applications requiring accurate and stable back-pressure control, particularly in oil & gas production, gas gathering, compressor stations, separators, heater treaters, and other process systems.

BelGAS Distributors CP P5300 Back Pressure Regulator

The P5300 utilizes an integrally mounted pilot system that provides sensitive pressure control and allows the main valve to respond automatically to changes in upstream pressure. When the upstream pressure increases above the pilot set point, the pilot causes the main valve to open, allowing additional flow downstream and reducing upstream pressure. When upstream pressure decreases toward the set point, the regulator modulates toward the closed position to maintain the desired pressure.

Operating Principle

The P5300 operates by sensing the pressure upstream of the regulator.

  1. Upstream pressure below set point
    The main valve remains relatively closed, restricting downstream flow and allowing upstream pressure to build.
  2. Upstream pressure reaches set point
    The integral pilot responds to the pressure signal and begins modulating the main valve.
  3. Upstream pressure increases above set point
    The pilot increases the opening of the main valve, allowing more medium to pass downstream.
  4. Upstream pressure decreases
    The pilot reduces the main valve opening, maintaining the upstream pressure close to the preset value.

The result is automatic and continuous upstream pressure regulation without requiring an external control system.

Construction

The P5300 is constructed as a globe-style pilot-operated regulator. The regulator can be configured with different port sizes and connection arrangements to accommodate the required flow capacity and installation requirements.

Available configurations include:

  • 2″ and 3″ body sizes
  • FNPT threaded connections
  • Class 150 RF flanged connections
  • Full-port design
  • Reduced-port design
  • Stainless-steel internal components
  • Integral pilot assembly
  • Various elastomer materials
  • Optional NACE MR0175 construction
