In industrial pipeline systems that require precise control of flow and pressure,Direct stroke electric actuatorWith its displacement output characteristics along a straight line, it has become the core regulating device for direct acting valves such as gate valves, globe valves, and diaphragm valves. This type of execution device converts electrical energy into axial linear motion, and achieves the lifting and lowering of the valve stem through transmission mechanisms such as screw rods and gears, with an adjustment accuracy of up to 0.1mm. It plays a role in high-pressure and high viscosity fluid control in fields such as petrochemicals, thermal power generation, and precision chemicals.

In the high-pressure pipeline system of the petrochemical industry, the pressure resistance and adjustment accuracy of linear electric actuators are particularly critical. The feed cut-off valve of the catalytic cracking unit needs to accurately control the flow rate under a high pressure of 10MPa. The actuator drives the ball screw through a servo motor to move the valve disc axially, achieving 0-100% flow regulation. Its dual sealing structure can withstand high temperature media (up to 450 ℃) inside the pipeline, ensuring long-term reliability under harsh working conditions.

In the steam system of thermal power plants, actuators are the "key nodes" that control steam parameters. The main steam gate valve of the boiler needs to adjust its opening according to the load of the steam turbine. The high-precision displacement control (resolution 0.01mm) of the linear actuator can accurately adjust the steam flow rate and stabilize the main steam pressure within the range of ± 0.1MPa. Its overload protection function can automatically shut down when the valve disc is stuck, avoiding motor burnout and reducing the fault handling time by 60% compared to traditional actuators.

The micro adjustment capability of linear electric actuators in precision chemical measurement systems meets the requirements of fine production. The feed diaphragm valve of the pharmaceutical intermediate reaction kettle requires precise control of the feeding amount (error ≤ 0.5ml), and the actuator is driven by a subdivision stepper motor to achieve micrometer level displacement adjustment of the valve stem. Its fully enclosed structure can prevent medium leakage and contamination, and when combined with food grade lubricating grease, it meets the hygiene requirements of FDA for pharmaceutical production equipment.

From high-pressure regulation to micro metering, linear electric actuators, with their advantage of linear displacement, have built the "linear regulation center" of industrial pipelines, providing stable and reliable technical support for precision production in various industries.
