Camco Single-Point Injection Orifice
Gas Lift Valves
Retrievable valves for continuous tubing flow production
APPLICATION
■■
Continuous tubing flow production
benefits
■■
■■
Reliable operation
Highly efficient and
economical performance
FEATURES
■■
■■
Field-proven design
Integral reverse-flow check valves
and replaceable floating and
nonfloating seats
An integral choke controls the flow of gas that passes through the
normally open Camco* single-point injection orifice gas lift valve into
the production tubing. This reliable line of valves comprises the 1-in
[25.4-mm] OD DKO-2, BKO-3, and OM-21R valves and the 11⁄2-in
[38.1-mm] OD RDO-20, O-21R, and O2-30-R valves. O2-30-R valves
have dual reverse-flow check valves. DKO-2 valves have nonfloating,
replaceable chokes, while the others have floating chokes. All the
valves contain integral reverse-flow check valves.
Port sizes
Port sizes for these valves are available in 1⁄16-in [1.6-mm] increments.
■■
■■
1-in [25.4-mm] OD valves:
––
DKO-2 valve ports are available from 1⁄8 to 3⁄8 in [3.2 to 9.5 mm].
––

11⁄2-in [38.1-mm] OD valves:
––
RDO-20 valve ports are available from 1⁄8 to 1⁄2 in [3.2 to 12.7 mm].
––
O-21R valve ports are available from 1⁄8 to 44⁄64 in [3.2 to 17.4 mm].
––
02-30R valve ports are available from 1⁄8 to 5⁄8 in [3.2 to 15.9 mm].
Operation
Injection gas enters the valve through the external ports between the
valve packing seats and travels through the choke, past the reverseflow check valve, and into the production tubing.
