BR-VT (HAS Vent Valve)
BR-VT HAS vent valve is a hydraulically actuated system that vents gas from the casing below a packer into the annulus to help maintain an optimum fluid level for an ESP. The system has an integral, built-in annulus valve installed above a multistring packer.
Pressure from the control line opens the valve to vent the gas, and pressure loss closes the valve and ends communication. Pressure applied to the annulus at a predetermined shear value opens the valve ports.
Features:
- Positive control-line pressure opens the valve.
- The valve vents gas from below the packer to maintain optimum fluid levels, protecting the ESP from excessive wear and burnout.
- The valve drains fluid from the tubing to remove hydrostatic pressure for safe ESP retrieval.
