Description
CAMTOP Pump Out Reverse Circulating Valve | 5K PSI | DST Equipment
5 inch / 4.25 inch / 6.25 inch
Product Overview
The CAMTOP Pump Out Reverse Circulating Valve is a hollow plug impact type circulating sub used in more difficult well testing operations, where depth and high-pressure differential across the plug sometimes make it difficult to open a conventional reversing sub.
The Pump Out Reversing Sub allows removal of free oil or gas in the pipe (minimizing the risk of fire) while the tool is coming out of the hole. It is also used to circulate and condition the drilling fluid when necessary.
The valve is equipped with a shear pin with plate as a backup device in case the plug cannot be broken by flute bar. By applying tubing pressure, the pin can be sheared by the pressure to establish communication.
