Abstract
One or more check valves may be used in a motor protector for an ESP assembly. Disclosed embodiments relate to a check valve adapter configured to provide additional versatility regarding such check valves. The adapter may have a first end portion, configured for removable attachment to an NPT screw-style vent port, and a second end portion configured to receive a cartridge-style check valve. The first end portion of the adapter is in fluid communication with the second end portion, and the second end portion can be configured to receive the cartridge-style check valve in either orientation, thereby allowing fluid flow through the adapter in either direction merely based on the orientation of the cartridge-style check valve. Systems for using an adapter with a cartridge-style check valve in an ESP assembly, as well as methods of controlling fluid flow in a motor protector using such an adapter, are also disclosed.
