KLD is a high-tech joint-stock enterprise specialized in manufacturing electric actuators and motorized valves. We have a first-rated team composed of professional research, management and sales. We obtained more than 80 independent intellectual properties and software copyright authorization, of which 3 are PCT international intellectual property. We strictly follow ISO9000 standard and the products have CE and other North America and EU’s relevant certifications. We have won more and more customers's trust by the unique charm of the design, function and superior quality, and exported to more than 50 countries all over the world.

Open is green LED, close is red LED, if it does not reach place(15s no reaching setting position), it will be considered as alarm(blue LED), of course, not only the LED indicator, you can also get alarm signal by dry contact signal.
Welcome all bright ideas, and we will realize your goal!

This video provides a visual demonstration of the high-precision control performance of the KLD Control Valve. Utilizing the industry-standard 4–20mA analog control signal, the valve achieves closed-loop precision regulation via a PID controller. On-screen, the valve’s display real-time synchronizes the setpoint and valve opening percentage, dynamically reproducing the adjustment process. This footage clearly illustrates the valve's rapid response, control stability, and exceptional regulation accuracy, vividly showcasing the precision and reliability of industrial automation control and offering a tangible experience of intelligent control efficiency in industrial applications.

KLD motorized valve features an auto-reset design — when powered on, the valve slowly opens to its fully open position; upon power loss, it automatically and gradually returns to the fully closed state.
The entire process requires no manual intervention. Reliable and safe — truly "opens on power, closes on power loss."
Whether it's an unexpected outage or routine shutdown, the valve always returns to a safe state automatically, adding an extra layer of protection to your system.
One take, real demo, what you see is what you get.
