Sitech Thetis exhaust valve

Sitech Thetis exhaust valve

The Thetis Exhaust Valve is a high performance valve suitable for all areas of recreational and technical diving. As with all SI TECH Exhaust Valves the Thetis is extremely sensitive for variations in pressure and provides the diver with excellent buoyancy control.

The design of the top lid makes it ideal to use in conjunction with heavy duty gloves and still evacuate proper amount of gas during ascent. All SI TECH Exhaust Valves has built in safety features that ensure no gas to be evacuated by accident while on surface. The construction of the filter lid makes the Thetis Exhaust Valve suitable to use in conjunction with all common undergarments.

Drysuit manufacturers have historically chosen to use large ( Ref. 11330) or small guide ridges ( Ref. 11340) in their drysuits for various reasons. To meet this, we offer the opportunity to chose between large and small guide ridge in our valves.
