1.1 PURPOSE

This specification was formulated to provide gas lift valves, reverse flow (check) valves, orifice valves, dummy valves and wireline retrievable valve mandrels (WRVM) that are consistently manufactured to a predictable level of quality. Technical content provides requirements for design, materials, tests and inspecting, welding, marking, storing and shipping. This specification is intended as a quality based specification and does not assure dimensional interchangeability between manufacturers.

1.2 APPLICATIONS

1.2.1 Equipment

This specification is for gas lift valves, reverse flow (check) valves, orifice valves, dummy valves and the WRVM's used as a receiver for these valves or other devices used to enhance oil well production or treat oil or gas wells. This specification is compiled such that the requirements for gas lift valves and WRVM's are in separate sections and unless indicated do not overlap requirements.
