Back Pressure Valve
• Designed to hold a column of fluid in coil tubing
• Adjustable opening pressure
• Spring loaded valve
• Opening pressure easily adjustable
• No ball drop required
• Easily redressable
The Hunting Back Pressure Valve enables the operator to keep a predetermined column of fluid in the tubing string irrespective of hydrostatic pressures.
The valve design is also fully adjustable and maintains a pressure tight seal in both low and high pressure environments.
To function the valve, the operator simply increases tubing pressure to the predetermined activation/hydrostatic pressure + down hole pressure. When this pressure is reached the valve opens allowing the fluid in the tubing to enter the well. The valve remains open until pumping ceases and the closing pressure is reached, at which point a column of fluid is maintained within the tubing string above the valve.
