UDT Tubing Retrievable Injection Pressure Operated Gas Lift Valves
UDT tubing retrievable injection pressure operated gas lift valves uses nitrogen charged, multi ply monel bellows to provide the force necessary to maintain the valve normally in closed position. These gas lift valves are installed in conventional mandrels for injection of gas into the tubing string. These valves are manufactured in variety of port sizes to suit a wide range of gas injection volume and flow rates. All the gas lift valves features floating valve seat, which facilitates seat change outs to make valve repair easier and more economical.

UDT Tubing Retrievable Gas Lift System
UDT TUBING RETRIEVABLE INJECTION GAS LIFT VALVES
UDT tubing retrievable reverse flow check valves, installed below gas lift valves, prevent fluid backflow into the annulus. Featuring spring-loaded darts and dual sealing—elastomeric and metal—they ensure safe, reliable well operation.
PMM CONVENTIONAL MANDRELS
UDT conventional gas lift mandrels feature external lugs for tubing-retrievable valves and protective guards for operational safety. Available in N-80, L-80, and P110 grades, they meet API 5CT standards for standard and sour services.
PMMTUBING RETRIEVABLE REVERSE FLOW CHECK VALVES
UDT tubing retrievable IPO gas lift valves use nitrogen-charged Monel bellows to stay closed, installed in conventional mandrels for gas injection, offering various port sizes and floating seats for easy, economical maintenance.
