PDK-1 Wireline Retrievable Dummy Valve |
|
FUNCTION
The Wireline Retrievable Dummy Valves (PDK -1) have 2 sets of
packing which fit in the seal bore of side pocket mandrel and isolate the casing
ports between tubing and casing annulus. In other words the valves are used to prevent
communication between the tubing and the casing.
APPLICATION
These Valves are used in side pocket mandrel to provide a positive seal between
casing - tubing annulus and to protect the mandrel seal bore until they are
retrieved by standard wireline methods. When installed, the PDK-1 Dummy Valves
eliminates unintentional placement of the other tools or debris in the mandrel
pocket.
