Overpressure relief valve OPRV for BCDs SMBs lift bags and other buoys Purpose and benefits Provides overpressure relief for BCDs, SMBs, lift bags and other buoyancy devices, helping to prevent accidental overinflation during inflation. Enables rapid venting of air as needed, allowing you to stay focused on safe diving rather than manage buoyancy surprises. Designed to rupture under excessive pressure to relieve overpressure, while remaining lightweight, strong, and portable. Construction and materials ABS body with a rubber washer and a corrosionresistant steel spring. Built to withstand seawater immersion and harsh marine environments. Compatibility and use Compatible with BCDs, SMBs, lift bags and other buoyancy devices used in diving. Attached with a drawstring lanyard for easy assembly and secure attachment. Specifications and performance Meets diving standards for overpressure relief in lifting bags and BCDs. Lightweight and portable without compromising strength or reliability. Practical use scenarios Predive setup: Install on BCD or lift bag to prevent accidental overinflation during inflation, ensuring a smooth start to the dive. Inwater adjustments: During buoyancy control, quickly vent air to finetune buoyancy without removing equipment. SMB deployment and lift bag operations: Use controlled venting to manage pressure during deployment, ascent, or retrieval, reducing risk of buoyancy issues. What you gain Enhanced buoyancy safety with a reliable, easytouse overpressure relief device. Durable construction suited for saltwater environments and routine diving use.
