The WRFV bleed sub assembly adapts to the top of a profile sub to efficiently allow

trapped pressure below a float valve or other type of injection valve to be bleed off safely.

The WRFV bleed sub assembly is designed to work in conjunction with the WRFV equalizing assembly.

The WRFV  bleed sub assembly works with both the model F and model G style float valve.

The WRFV bleed sub assembly comes with a 1502 outlet union as standard equipment, this

allows the user to attach to existing pump lines and bleed off to the desired location.

Applications:

Used during Under-balanced or Managed Pressure Drilling operations to safely and efficiently

bleed trapped pressure from below wireline retrievable float valves so equipment can be safely removed for the drill string during tripping operations.
