The valve body and wetted components are manufactured from AISI 316L stainless steel to ensure outstanding resistance to high ozone concentrations, moisture, and corrosion. Internally, the valve features an ozone-resistant fluoropolymer spring, piston/disc, and seals that maintain consistent performance in aggressive environments.

This PSV is engineered and tested in compliance with API 520 (Sizing and Selection of Pressure-Relieving Devices) and API 526 (Pressure Relief Valve Dimensions) standards, providing predictable set pressure accuracy, controlled overpressure, and sufficient relief capacity for the protected pipeline or pressure vessel. The design incorporates precision spring materials and a robust sealing interface to ensure minimal leakage and long service life in ozone-rich atmospheres.
