Conventional Pilot-Operated Valves

Gas lift valves for intermittent tubing flow production

Maximize production in intermittent tubing flow applications

Camco gas lift and subsurface safety systems include conventional pilot-operated gas lift valves used for intermittent tubing flow production. Each pilot-operated valve consists of a pilot section and a power section. A nitrogen-charged, multi-ply MONEL bellows provides the force necessary to maintain the pilot section in a normally closed position, and an INCONEL spring provides the force necessary to maintain the power section in a normally closed position.

This line of valves includes the 1-in [25.4-mm]-OD BP-2 valves and the 1 1/2-in [38.1-mm]-OD CP-2 valves. Both of these valves have floating valve seats.

Power section of BP-2 valve has a flow area equivalent to a 3/8-in [9.5-mm] port. Port sizes for BP-2 pilot section available in 1/16-in [1.6-mm] increments from 3/16 to 3/8 in [4.8 to 9.5 mm].
Power section of CP-2 valve has a flow area equivalent to a 9/16-in [14.3-mm] port. Port sizes for the CP-2 pilot section available in 1/16-in increments from 1/4 to 1/2 in [6.4 to 12.7 mm].
