SI Tech Thetis Exhaust Valve

The Thetis exhaust valve is a high-performance valve suitable for all types of recreational and technical diving. Like all SI TECH exhaust valves, the Thetis is highly sensitive to pressure variations and provides excellent buoyancy control.

The top lid design makes it ideal for use with heavy-duty gloves, while still allowing the correct amount of gas to be released during ascent. All SI TECH exhaust valves feature built-in safety mechanisms that prevent accidental gas release at the surface. The filter lid construction makes the Thetis valve compatible with all common dry suit undergarments.
