Injection Pressure Operated Valve (IPO). Unsurpassed reliability and enhanced well integrity.
SafeLift & IsoLift IPO valves employ unique bellows technology, which ensures reliable operation throughout the life of the field.
Unloading valve reliability issues often arise as traditional bellows systems have major limitations when it comes to pressure, open & close cycles and temperature. These effects are more pronounced in deeper, hotter wells.
PTC has developed a revolutionary dual operating bellows system that once installed in a gas lift valve can be charged to more than 12 500 psi. The system is built such that the stem tip is lifted a full ¼" off the seat during unloading operation, not a fraction of an inch, which is typical in the industry. This enables SafeLift & IsoLift IPO valves to be used as operating valves.
IPO valve section has been tested to more than 50 000 full open/close cycles. SafeLift’s & IsoLift’s true metal-to-metal seal has been used as a well barrier for operators worldwide. It was designed, built and tested in accordance to API 19G part 2 and leak tested in accordance to ISO 14310-V1/V0. SafeLift valves are designed to be installed inside all side-pocket mandrels with 1.0" & 1.5" seal bores in accordance with API 19G part 1.

Life of Field Gas Lift Design
Petroleum Technology Company, have developed a unique gas lifted well design work-flow, which employs a combination of proprietary and industry recognized software tools. These tools cater for uncertainties and changes in key parameters over the life of the field. PTC’s design tools provide operators with all the information they require, to make the best gas lift design selection decisions.
