SI TECH Argo Exhaust Valve for Drysuits

Precision Venting. Ultimate Buoyancy Control.

The SI TECH Argo Exhaust Valve is a high-performance, adjustable purge valve designed for the most demanding areas of recreational and technical diving. Renowned for its extreme sensitivity to pressure variations, the Argo provides divers with unparalleled buoyancy control. Whether installed on a heavy-duty drysuit or used on a rebreather, this valve is engineered for a smooth, high-flow release of expanding gas during your ascent, ensuring a safe and controlled return to the surface.

Ergonomic Design & Uncompromising Safety

Diving in frigid waters requires gear you can easily manipulate. The Argo features a specialized top lid designed with an adjustable ratchet action, making it incredibly easy to grip and fine-tune even when wearing thick, heavy-duty dry gloves. The internal filter lid is constructed to work flawlessly in conjunction with all common undergarments, preventing snagging or blockages. Furthermore, all SI TECH exhaust valves feature built-in safety mechanisms that ensure no gas is accidentally evacuated while you are floating on the surface.
