The HPV manual needle valve (with a visualized control solution) is an innovative product developed by the KIYAN team to address the needs of traditional industries.
In industrial settings, conventional needle valves are widely used for flow or pressure regulation, but they often require long periods of manual adjustment by operators. The adjustment results typically depend on the operator’s experience, lacking consistency and digital control capabilities.
To solve this issue, we developed a simple digital upgrade solution: by removing the manual handle and installing a stepper motor on the shaft, combined with our controller, the needle valve’s opening can be precisely controlled via digital signals (0–10V, 4–20mA, RS485).
The product also features a built-in position sensor, allowing real-time monitoring of valve operation to ensure complete closure, prevent step loss, and greatly improve reliability and ease of use.
This solution transforms traditional manual needle valves into smart, automated proportional valves, enabling production lines to quickly implement digital upgrades.
