Product Description

The A28H and A28Y series safety valves are spring-loaded, full lift type valves equipped with a manual test lever, designed for reliable overpressure protection in industrial systems. These valves are suitable for use with air, steam, and gas media, automatically releasing excess pressure when system limits are exceeded.

The integrated lever allows for manual operation and testing of the valve to verify functionality during maintenance or inspection. The A28H type is suitable for general media such as air and steam, while the A28Y/P/R variants are designed for corrosive media applications.

The valve operates using a calibrated spring mechanism, ensuring accurate opening at set pressure and resealing once normal pressure conditions are restored. The full lift design allows for higher discharge capacity compared to low lift variants.
