The ESD emergency shutdown valve's pneumatic-hydraulic actuator operates using pipeline natural gas or nitrogen as the power source and hydraulic oil as the transmission medium, driving the pipeline valve to open and close.

The API6D toggle-type gas-liquid linkage actuator features all the functions of its counterparts. Additionally, we optimize the product based on the characteristics of domestic pipeline field operations, utilizing our extensive field experience. Particularly, the special design for torque ensures a high degree of matching with the torque of ball valves, thereby guaranteeing the safety of the valve during operation. In terms of details, we adopt industry-standard low-temperature display, wireless data download, and mobile SMS alarm technologies, filling the gap in the functional aspects of both domestic and international products. Regarding quality, we have specially designed a torque testing station for different types of actuators, conducting scientific tests on every unit produced to ensure product quality.

The company strictly adheres to rigorous management for every actuator, covering product design, raw material procurement, production processing, pre-delivery inspection, and after-sales service guidance, ensuring full traceability for each actuator throughout its lifecycle.
