BZSV HTDO/HTDB Large Diameter Safety Valve – 10" to 20", Class 150–300

The BZSV HTDO/HTDB Series Large Diameter Safety Valves are engineered for critical overpressure protection in large-scale petrochemical, chemical, and storage tank applications. Available in sizes from 10" V14" to 20" BB24", these safety valves are specifically designed to handle very high flow capacities while maintaining a compact footprint. A single 20" BB24 valve delivers the equivalent displacement of six standard 8" T10 safety valves, significantly reducing installation costs and space requirements. These valves feature a lightweight construction with robust sealing performance and are fully compliant with ASME Boiler and Pressure Vessel Code Section VIII for pressure relief devices. Their economical yet efficient design makes them ideal for protecting high-volume vessels and storage systems.
