The SR Series and JR Series gas lift mandrels are tubing retrievable mandrels installed as an integral component of the tubing.
Full, open flow area (same as tubing I.D.)
Guard plates and lug protect valve from damage during installation
Various materials and thread connections provide compatibility with all current production tubing
Available in sizes from 21⁄16" to 41⁄2" O.D. (production string)
SR Series: the mandrel's external ported lug is configured for 11⁄2" O.D. tubing retrievable gas lift equipment.
JR Series: the mandrel's external ported lug is configured for 1"O.D. tubing retrievable gas lift equipment.
The IM Series gas lift mandrels are also installed as an integral component of the tubing string, but unlike the SR and JR Series, they feature internally mounted gas lift and check valves. The IM mandrel has the same O.D. dimensions as the tubing, making it ideal for special applications:
Wells with limited clearance between tubing and casing
In the injection string for casing flow
In the production string for tubing flow with a reverse flow valve
Available in sizes from 11⁄4" to 27⁄8" O.D. (production string)

PCS Ferguson offers a comprehensive line of valves and accessories for either injection pressure or production pressure operation. Designed to anticipate changes in well characteristics and manufactured to the highest quality standards, our gas lift and check valves offer exceptional performance and reliability over the life of the well.
TP Series: tubing retrievable, injection pressure operated gas lift valves.
Large dome volume improves operating efficiency
Port sizes from 1⁄8" to 1⁄2" for optimum gas passage
Constant or intermittent flow
Mechanical travel stop increases the cycle life of the bellows
Three-ply Monel® bellows extends life
Replaceable floating Monel® seat (tungsten material available)
Available in 5⁄8", 1" or 11⁄2" O.D.
TC Series: tubing retrievable, spring-loaded check valves that provide casing protection from back flow through the gas lift injection valve.
Eliminates the need to re-unload casing liquid by preventing casing fill-up during shut down
Stainless steel or Monel® material
Combination resilient (metal-to-metal) seat for bubble-tight seal
