Overview

The Dive/Surface Valve (DSV) is a mouthpiece valve used to switch between dive and surface positions on a breathing loop. It helps protect the loop from water entry when the mouthpiece is removed and supports controlled transitions between modes. Commonly used on rebreather and other loop-based systems; verify compatibility with your equipment.

Key Features

• Switches between dive and surface positions at the mouthpiece
• Helps minimize water ingress into the breathing loop
• Designed for use with loop-based breathing systems (e.g., rebreathers)

Notes

• Confirm fit and compatibility with your specific unit before purchase.
• Rinse thoroughly with fresh water after use and follow your equipment’s maintenance schedule.
