basic information
**Features** 1. Zero liquid leakage level enhances safety Significantly contributes to ensuring worker safety and maintaining the environment in workplaces handling chemicals such as electrolytes. It also greatly reduces the risk of contamination in clean environments. 2. Low pressure loss even at high flow rates Minimizes losses in the flow path, contributing to improved production cycle times. 3. Reduction of liquid loss and costs during line switching Since almost no residual liquid occurs during connection and disconnection, it reduces waste of expensive electrolytes, shortens removal and cleaning times, and decreases liquid recovery work, contributing to cost and labor reduction. 4. Prevention of incorrect connections and liquid leakage issues A robust structure and reliable locking mechanism prevent operational mistakes during line switching and liquid leakage due to unexpected disconnections.
