Fleyenda Flow Electric Actuator Type: On/Off, Regulating, Intelligent

Fleyenda Flow Electric Actuator Type: On/Off, Regulating, Intelligent

Sep.26.2025

Fleyenda Flow offers a versatile range of FLE electric actuators, designed to meet different levels of control and operational needs. Customers can choose from three types of actuators: On/Off, Regulating, and Intelligent, each providing tailored functionality for industrial applications. This article explains the similarities and differences between these three types.

The On/Off type actuator is the most straightforward option. It is designed for simple open and close operations, making it reliable and cost-effective for systems where precise flow control is not required.

The Regulating type actuator builds upon the On/Off model by adding precision adjustment capabilities. This allows operators to fine-tune valve positions, ensuring smoother control of flow, pressure, or other process variables. It is ideal for industries where more accurate regulation is critical to system performance.

The Intelligent type actuator takes functionality a step further. In addition to the regulating features, it is equipped with an LED display and local adjustment capability. Operators can monitor and adjust actuator settings directly on-site without returning to the PLC or control room, which greatly enhances convenience, efficiency, and operational flexibility.

By offering these three types, Fleyenda Flow ensures that customers can find the most suitable actuator solution, whether for basic automation, precision flow control, or intelligent field operation.
 

The following is a comparison table of three types of electric actuators:
Type Control Function Control Signal Accuracy Additional Advantages
ON/OFF Open / Close only (0° / 90°) 4–20 mA / 0–10 V / 1–5 V No flow or opening adjustment Simple operation, suitable for binary shut-off applications
Regulating Adjustable opening (0°–90°) 4–20 mA / 0–10 V / 1–5 V Basic error ±0.5%
Return difference <0.3%
Dead band 0.1–1.6%
Damping 0
Mechanical repeatability 0%
Precise flow control compared to ON/OFF type
Intelligent Adjustable opening (0°–90°) with intelligent control 4–20 mA / 0–10 V / 1–5 V Basic error ±0.5%
Return difference <0.3%
Dead band 0.1–1.6%
Damping 0
Mechanical repeatability 0%
LED display for on-site adjustment
Real-time monitoring and on-site adjustment without returning to PLC/DSP room
