CONVENTIONAL GAS LIFT VALVE -IPO (TUBING RETRIEVABLE VALVE)
KI 02-40-1000 (‘G-40’ GLV)
KI 02-20-1000 (‘G-20’ GLV)
DESCRIPTION
G-Series conventional gas Lift valves are Nitrogen charged gas lift valves which can be used as an intermittent valve or a continuous flow valve. This valve is installed with a reverse check valve on the conventional tubing retrievable gas lift mandrel. Dome pressure is set in a shop at a reference temperature and corrected to an operating depth temperature. The nitrogen charge inside the bellows provides a downward force tending to hold the valve on its seat.
gas lift valves has ½”-14 NPT Pin connection to suit Reverse flow check Valves and these are available in various port sizes as required.
ADVANTAGES
Vibration protected 3-ply Monel bellow are designed to withstand hydrostatic pressure up to 5000 psi. Nitrogen dome charge, acting on the O.D. of the bellows, permits bellows to expand uniformly without stacking, thus prolonging bellows‟ life. The multiple port size availability, make this valve series appropriate for a wide range of operating conditions.
OPERATING PRINCIPLE
The nitrogen charged dome applies pressure to the external area of the bellows provides the downward force, holding the valve on its seat. This dome pressure is preset at the reference temperature and corrected to operating temperature. The opening forces on the valve are the casing pressure acting on the internal area of the bellows (less the area of the seat) and the tubing pressure acting on the seat area. When the combined Casing & Tubing pressures are sufficient, the valve opens. Once the valve is open, it remains open until the casing pressure is reduced to predetermined closing pressure.
The spread (the difference between opening & closing casing pressure) is controlled by the tubing sensitivity of the valve. The larger the seat port area, the more tubing sensitive the valve is.

REVERSE FLOW CHECK VALVE
KI 02-90-1000 (‘G-40’ RFCV) KI 02-70-1000 (‘G-20’ RFCV)
DESCRIPTION
G-Series Reverse flow check valves (RFCV) are used with conventional gas Lift valves and Mandrels. The RFCV assembly utilizes the same metal to metal seal as well as metal dart to soft Hy- car pad seal as does the retrievable valve checks. The check is a velocity type check requiring flow pressure to force the dart on seat but is also available in a normally closed variation with a spring attachment.
Reverse flow check valves (RFCV) have ½”- 14 NPT internal and external threaded connections to suit conventional Gas lift Valves and Mandrels respectively.
ADVANTAGES
The RFCV protect the casing from backflow, allowing the tubing to be pressurizing in various procedures, and prevent any comingling of fluids in dual installation for a wide range of operating conditions.
