Product Description

The WA42 series safety valve is a spring-loaded, bellows type valve designed in accordance with American standard requirements for reliable overpressure protection in industrial systems. The valve automatically opens when system pressure exceeds the set limit, releasing excess pressure, and reseals once normal operating conditions are restored.

The integrated bellows design provides isolation between the spring mechanism and the process media, improving sealing performance and protecting internal components from corrosion and contamination. This makes the valve suitable for applications involving corrosive, toxic, or high-purity media.

The valve operates using a calibrated spring mechanism to ensure accurate pressure response and stable resealing performance. Its enclosed construction supports controlled discharge, while the flanged connection allows for secure installation within pipeline systems.
