Say goodbye to adjustment headaches! Navarch Smart Linear Actuators unlock a new level of building automation experience.

In building automation systems such as central air conditioning and district heating, precise regulation of medium flow directly determines temperature control effectiveness and energy efficiency. Traditional actuators often suffer from control deviations, cumbersome maintenance, and poor adaptability, becoming stumbling blocks to stable system operation. Navarch’s intelligent linear actuator emerges as a game-changer, delivering efficient and reliable solutions for industrial and building control applications through cutting-edge technology and user-centric design.

Core Advantages, Redefining Intelligent Regulation

Precision control with near-zero error: The actuator and valve stem feature a gap-free connection mechanism, paired with an automatic stroke calibration function upon power-up. Each startup automatically calibrates the valve stem stroke, minimizing control error to achieve high repeatability control at 0.1%, ensuring more precise regulation of medium flow.

Multi-mode control for flexible and convenient operation: Supports three modes—RS485 remote control (Modbus protocol), 4-20mA/0-10VDC proportional control, and floating-point control—switchable via on-site DIP switches to accommodate diverse requirements such as remote monitoring and local operation. Manual functionality facilitates field maintenance and debugging, enabling operation without complex tools.

Exceptionally durable for harsh environments: Withstands 100,000 switching cycles without failure, delivering a service life far exceeding industry averages. Featuring IP67 protection and optional electric heating, it operates reliably across a wide temperature range from -25°C to 65°C and in high-humidity, non-condensing conditions—unfazed by extreme cold and other demanding scenarios.

Reliable and dependable, never letting you down when it matters most: Equipped with a power-fail reset function, it automatically drives the valve to fully open or fully closed positions during sudden power outages, preventing system failures from escalating. Automatic alarms for motor overcurrent, jamming, and other faults provide real-time operational status feedback, reducing maintenance costs.

Multi-scenario adaptability unlocks extensive application possibilities

Whether regulating water temperature in central air conditioning systems, controlling flow in heating networks, or ensuring precise medium delivery in industrial automation, the Navarch

Smart Linear Actuator delivers seamless compatibility. With rated torque ranging from 1000N to 5000N across multiple specifications and support for 24VAC/DC and 220VAC wide voltage inputs, it pairs flexibly with various electric control valves. Widely deployed in commercial buildings, factory workshops, hospitals, schools, and more.
