Product Overview
The WITT AV619 is a high-precision gas safety relief valve engineered for reliable overpressure protection in industrial gas supply and process systems. Manufactured by WITT, a globally recognized specialist in gas control and safety technology, this valve operates on a direct spring-loaded principle, automatically venting excess pressure to atmosphere when system pressure exceeds the preset threshold. Once downstream pressure returns to a safe level, the valve reseats to maintain a tight, leak-free seal. The AV619 serves as a critical safety component in pneumatic and process gas circuits, protecting downstream instrumentation, piping, and equipment from hazardous pressure surges while ensuring continuous, compliant operation.
