Key features and benefits

Valve automation control—from "manual operation" to "remote control"

Loading and unloading operations for tanker trucks often take place at gas stations, chemical plants, oil depots, and similar locations, where operators must frequently climb onto the tanker trucks to manually rotate valves. Our linear actuators can precisely control the opening and closing of various types of valves—when the actuator extends, the valve opens and material loading or unloading begins; when the actuator retracts, the valve closes and the operation stops. Operators no longer need to climb the tanker themselves; they can precisely control the valves simply by pressing a button on the control panel or issuing commands via a remote control platform. This change not only significantly improves loading and unloading efficiency but also fundamentally eliminates safety hazards associated with working at heights.

Precise stroke control for stepless adjustment of valve opening

Different materials require different valve openings during loading and unloading—high-viscosity materials require a wide opening to accelerate flow rate, while low-viscosity materials require a narrow opening to prevent splashing. Our linear actuators provide precise stroke control and extremely high repeatability, allowing the valve to stop precisely at any opening position. Operators can adjust the valve to the optimal opening based on the characteristics of the material being loaded or unloaded, effectively controlling flow rate and pressure while ensuring loading and unloading efficiency.

Explosion-proof design for confident operation in flammable and explosive environments

The materials transported by tanker trucks are primarily flammable and explosive liquids such as gasoline, diesel, and chemical solvents, which impose extremely stringent explosion-proof requirements on electrical equipment. Our linear actuators can be customized with explosion-proof designs according to customer needs. They prevent spark leakage under overload conditions and resist fire and explosions when exposed to open flames, fundamentally eliminating the risk of electrical equipment becoming an ignition source. Explosion-proof electric actuators ensure that the automated control of tanker truck valves is truly "fail-safe."

High protection rating, resistant to harsh outdoor weather

Tanker trucks operate outdoors year-round, and loading and unloading operations are often conducted in open-air environments, facing the challenges of harsh natural conditions such as sunlight, rain, wind and sand, and salt fog. Our linear actuators feature a high protection rating, providing full resistance to the intrusion of moisture and dust. Constructed from corrosion-resistant materials and featuring a fully sealed design, they ensure stable and reliable performance even during long-term outdoor use.

Long service life and maintenance-free operation, reducing total lifecycle costs

Tanker trucks are high-frequency transport vehicles, and any downtime caused by equipment failure can result in significant economic losses. Our linear actuators feature a maintenance-free design, eliminating the need for regular lubrication or replacement of wear-prone parts. The all-electric solution completely eliminates the risk of oil leaks in hydraulic systems and the issue of aging tubing in pneumatic systems. Validated through tens of thousands of endurance tests, they ensure stable operation throughout the vehicle's entire lifecycle, minimizing maintenance requirements.

Low-power operation, compatible with onboard power systems

The electrical systems of tanker trucks are typically powered by onboard batteries, which impose strict energy consumption requirements. Our electric actuators consume power only during the instant of valve operation; in standby mode, power consumption is extremely low, placing no additional burden on the vehicle's battery.

Smart integration, enabling remote monitoring and management

The electric actuator provides precise position feedback and can be integrated with the vehicle's control system or a remote management platform via a smart interface. By combining the actuator's position feedback data with the loading and unloading management system, companies can remotely monitor and manage tanker loading and unloading operations—from real-time monitoring of valve opening to precise tracking of loading and unloading progress, ensuring every step is executed accurately under digital management.

Built-in Hall sensors enable precise customer control

Our actuators feature built-in Hall sensors that provide real-time feedback on stroke position and operational status via pulse signals. Based on this data, customers' control systems can precisely monitor real-time valve opening and achieve accurate closed-loop control. The real-time feedback from the Hall sensors provides a precise basis for controlling loading and unloading operations—from the moment a valve opens to confirmation of its complete closure, every step is executed with precision under closed-loop control.
