- Constructed from a durable ABS body, rubber washer, and corrosion-resistant steel spring, this product is built to endure harsh marine environments, easily withstanding immersion in seawater. - Designed with a scientific approach, our equipment prioritizes user comfort while utilizing high-quality materials for enhanced performance. - This pressure relief system is compliant with diving standards, providing overpressure relief for lifting bags and buoyancy control devices (BCDs). It is lightweight, robust, and highly portable, making it an essential tool for divers. - The overpressure relief valve (OPRV) is compatible with BCDs, surface marker buoys (SMBs), lift bags, and other buoy devices. Easily attachable with a drawstring lanyard, it simplifies setup and usage. Use Scenarios: 1. When diving in challenging conditions, this device ensures your BCD maintains optimal buoyancy, preventing overinflation and enhancing safety. 2. Utilize the OPRV during underwater recovery operations to effectively manage lift bags, ensuring controlled ascent and stability of heavy loads. 3. Ideal for scuba diving schools and rental facilities to enhance the safety and reliability of their equipment during training sessions and excursions.
