POWERFLOW 1500 series intelligent valve positioner, our best-selling product since its market launch in 2015, has been widely adopted in pharmaceutical, food processing, textile dyeing, and other industries for its exceptional reliability and cost-effectiveness, receiving high praise from numerous customers. However, in some complex field environments where the top cover was missing or improperly secured (accounting for approximately 0.61% of total sales, attributed to user operation), water ingress could potentially occur, leading to circuit board damage. 

To completely eliminate this issue, enhance product reliability, and improve user experience, we decided to invest in mold upgrades on the tenth anniversary of the launch of 1500. The improved version will achieve IP67 waterproof rating even without the top cover installed, which is in line with the waterproof standards of our other products.

The upgraded product will complete its market replacement by the end of June 2025. There will be subtle changes in its appearance, but the improvement costs will be absorbed by our company without any price adjustment. The product improvement marks a further enhancement in reliability, fully aligning with our company's product design and business philosophy of "Reliability-First". We remain committed to this principle, continuously driving product iterations and upgrades to provide the most reliable solutions to our customers.
