Apeks High Profile Drysuit Dump Valve

Effortless Ascent. Complete Control.

The Apeks High Profile Drysuit Dump Valve is a top-performing, legendary component trusted by technical and cold-water divers worldwide. Responsible for the controlled release of gas during your ascent, this valve is crucial for maintaining stable buoyancy—especially when operating under changing pressures with a thick undersuit. Designed for standard installation on the left arm of your drysuit, it dramatically lowers the risk of an uncontrolled "shoot-up" to the surface, ensuring a calmer, safer dive.

Automatic Operation with Manual Override

This advanced valve gives you two reliable methods for controlling your gas. Once the internal spring is correctly adjusted, the expanding air automatically vents from the suit on its own during your ascent, allowing for hands-free operation so you don't have to take your hands off your guideline or inflator. Additionally, it features a manual over-ride system—simply press the mushroom button to quickly empty excess gas for trim correction without disturbing your automatic buoyancy setting. The ergonomically designed high-profile cover features an improved ratchet feel and is specifically shaped to be easily operated even when wearing thick, cold-water gloves.
