How to Set the Hysteresis of the Actuator?

Setting the hysteresis allows the actuator to better match PID closed-loop control applications. Steps to Set the Hysteresis: Turn the S-A switch (highlighted in the red box below) to position 2. Rotate the adjustment knob (highlighted in the yellow box) to set the hysteresis. Each scale mark represents 0.5%. The adjustable hysteresis range is 0.5% […]

What type of valves can DCL electric actuators drive?

The DCL electric actuator is mainly used to drive butterfly valves with a diameter of less than 600mm, ball valves with a diameter of less than 350mm, and ventilation dampers and air flap valves with a diameter of less than 1200mm. Beyond these applications, some interesting use cases are also worth noting. For example: Rotating […]

How does an electric actuator works?

Once connected to a power supply (AC380V, AC220V, AC24V, or DC24V), DCL electric actuators can be controlled by a Distributed Control System (DCS) using various control signals, including analog signals, digital signals, bus communication, and IoT networks. The actuator drives the electric valve to fully open, fully close, or adjust to a specified position, enabling […]

Why choose an electric actuator?

An electric actuator utilizes a motor-driven reduction mechanism to achieve both rotary and linear motion of a valve. Since it is powered by a motor, the electric actuator features a simple and reliable structure without requiring additional support systems like pneumatic or hydraulic sources. This results in higher energy efficiency and lower operational costs. At […]

5 Steps to Start Using DCL Actuator

1. Install actuator onto the valve Turn the valve in fully closed position. Install the bracket on the valve. Connect the coupling on the valve shaft. Drive the actuator to the fully closed position with manual handle. Insert the actuator output shaft into the square hole of the coupling. Tighten the connecting between these parts. […]
