Did you know
- Star Marine Tech's SMT-PV high-velocity pressure-vacuum relief valve is designed for use in marine oil and chemical tankers, adhering to IMO and IBC regulations.
- The SMT-PV is a high-velocity pressure-vacuum relief valve, distinguishing it from standard pressure-vacuum valves by its ability to maintain an efflux velocity of at least 30 m/s. Star Marine Tech also offers specialized versions, including PV valves with gas-free covers, force-closed devices, and heating elements for cold environments.
- The SMT-PV valve provides automatic control of pressure differentials during cargo loading, voyages, ballasting, and de-ballasting without manual intervention, and offers auto-protection against fire and explosions on deck. It is designed to prevent excessive vacuum when the inert gas system cannot supply gas promptly.
