Exploring the Industry Transformation and Prospects of Gas-Over-Oil Actuator

The fundamental concept of the Gas-Over-Oil  Actuator

In modern industry, the Gas-Over-Oil  Actuator has become an indispensable component. Simply put, it is an actuation device that combines the use of both gas and liquid, making it widely applicable in control systems. Whether in automated production lines or complex mechanical equipment, this type of actuator consistently delivers remarkable performance. As a leader in this field, Chengdu Mikeson Flow Controls Mfg. Co., Ltd. has deeply embraced and implemented this concept—its pioneering Gas-Over-Oil  Actuator operates on the core principle of "pressure as power," directly leveraging the inherent pressure within the pipeline to drive valve movements without requiring an external power source. This innovative approach perfectly embodies the essence of efficient gas-liquid synergy. Established in 2011, the company has grown into a national high-tech enterprise and has even taken the lead in drafting standards for actuators and actively participating in relevant technical committees. Through its technological innovations, the company has redefined the core value of modern gas-liquid actuation equipment.

Widely applied across industries, with limitless potential.

Imagine a high-speed production line where pneumatic-hydraulic actuators can swiftly respond to various commands, ensuring optimal production efficiency. Particularly in industries such as oil and chemical processing, the application of this equipment proves especially seamless and effective. By leveraging gas pressure to precisely regulate liquid flow, these actuators deliver unparalleled precision—truly making them an indispensable "treasure" in modern industrial operations. Chengdu Mikeson's pneumatic-hydraulic actuators take this "treasure" to the next level, maximizing its value through cutting-edge technology. Their products have demonstrated exceptional environmental adaptability, earning widespread adoption in core projects undertaken by industry giants like China National Pipeline Group, PetroChina, and Sinopec. From national-level long-distance pipelines such as the West-to-East Gas Transmission Project and the Sichuan-to-East Gas Transmission Initiative, to on-site operations in the Changning shale gas development area, Mikeson's equipment has consistently proven its reliability. Even under challenging conditions—such as the frigid, oxygen-deprived environment of the Qinghai-Tibet Plateau, where their self-powered, non-electric design eliminates the need for external power supplies; or in Xinjiang's Gobi Desert, where extreme temperature fluctuations pose significant risks—Maikesen's actuators have excelled, overcoming traditional leakage issues through advanced sealing technologies. These achievements underscore the irreplaceable role of pneumatic-hydraulic actuator technology in handling complex operational scenarios.

Technological advancements drive industry transformation.

With the rapid advancement of technology, gas-liquid linkage actuators are continuously being upgraded. The application of new materials and the integration of intelligent control technologies have significantly enhanced the stability and reliability of these devices. Notably, the trend toward智能化 (smartification) enables these actuators to perform self-diagnosis and automatic adjustments, greatly reducing the need for manual intervention. Chengdu  Mikeson is at the forefront of driving this technological transformation. Its independently developed DG series of gas-liquid linkage actuators features an internationally pioneering parallel dual-guided rocker-arm transmission structure. By fixing the trajectory of the transmission slider, this design eliminates piston shaft deformation during movement, ensuring 100% lossless transfer of hydraulic cylinder thrust and boosting transmission efficiency by more than 30%. This innovative design, protected by a PCT international patent, fundamentally transforms the traditional force transmission mechanism of rocker-arm actuators, enabling product output torque ranging from 20 Nm to 600,000 Nm while maintaining operational resilience across extreme temperature ranges—from -55°C to 150°C. In 2021, its 600,000-newton-meter Gas-Over-Oil  Actuator successfully passed the evaluation conducted by the China Machinery Industry Federation, earning recognition as "filling a domestic gap and reaching international advanced levels." Furthermore, it was awarded the second prize in the Technical Invention category of the "China Machinery Industry Science and Technology Award," effectively breaking the monopoly held by European and American companies in the high-end market segment. In terms of intelligent upgrades,  Mikeson remains a leader in the industry. With four newly registered national software copyrights added in 2025, the company has seamlessly integrated gas-liquid linkage verification with advanced intelligent control algorithms. The resulting monitoring system enables real-time collection of equipment operating parameters and precise speed regulation. Coupled with remote diagnostic capabilities, this innovation shifts equipment maintenance from a reactive "emergency repair" model to a proactive "early warning" approach, significantly cutting down on labor-intensive intervention costs.
