Product Overview

The Dual Valve Lubricator is a high-standard wellhead servicing device designed in full compliance with API 6A and API 11 PL international industry specifications, specially developed for onshore and offshore oil and gas well plunger lift operations, well intervention, routine maintenance and downhole tool running and retrieving work. As a core wellhead Auxiliary Equipment, it features an integrated dual-valve structural design, effectively solving the safety and efficiency pain points of traditional single-valve lubricators in high-pressure well operation scenarios. Equipped with two sets of independent sealing control valves, the product realizes dual isolation and staged pressure relief, achieving safe launching and salvaging of plungers, wireline tools and downhole accessories under live well pressure conditions without well shutdown, which greatly improves the continuous production capacity of oil and gas fields. Manufactured with high-quality alloy steel forgings and processed through overall heat treatment and precision machining, the dual valve lubricator features high structural rigidity, excellent pressure resistance and reliable bidirectional sealing performance. The internal flow channel adopts a streamlined optimized design, which reduces fluid resistance and avoids debris accumulation, ensuring smooth tool passing and well fluid circulation. All sealing components adopt high-temperature and corrosion-resistant composite materials, adapting to harsh working environments such as high pressure, high temperature, hydrogen sulfide corrosion and salt spray erosion in oil and gas wells. The modular assembly structure supports quick disassembly, installation and on-site maintenance, with reserved detection and pressure relief ports to realize safe pressure release and real-time condition monitoring during operation. Compared with conventional lubricators, the dual-valve dual-isolation structure effectively eliminates wellhead pressure leakage risks, improves overall operation safety, and is suitable for long-term continuous operation of various conventional and special oil and gas wells, becoming an essential safety supporting device for modern well control and well servicing operations.
