Product Overview

This is a 6 mm air charging valve with shut-off function, designed for differential-pressure air systems and reliable sealing after inflation.

Specifically designed for air refueling scenarios, this device integrates refueling control and shut-off functions. Its precise 6mm nozzle diameter is suitable for low-flow refueling needs, and it can stably withstand internal pressure differentials of 2 bar and external pressure differentials of 20 bar. Balancing structural stability and ease of operation, it is widely used in various air refueling systems to accurately control medium flow, shut-off, and refueling, ensuring a safe and efficient refueling process.
