The T-VALVE can rotate a full 360 degrees, allowing for a wide range of hose configurations. Thus, it truly doesn’t matter if one rig routes the drysuit hose under the right arm and another under the left.

We also used a virtually unbreakable E/O cable. Thanks to its coaxial structure with an extended cross-section of the copper conductor, we achieved reduced resistance, which improved the performance of the entire heating system.

Ammonite System T-VALVE has also a very low profile, streamline construction and features a domed form to limit the snag hazard regardless of where the valve is positioned.

Thanks to an extra-large recessed push-button it is effortless yet controlled to operate even with thick gloves or cold hands.

The thermo valve is robust due to its nickel-plated brass and stainless steel components. The carefully designed structure contributes to reduced wear on the seals and overall exceptional durability.

The extra-large recessed push-button is effortless yet controlled, making it easy to operate even with thick gloves or cold hands. Moreover, the strong spring of the push-button ensures precise and progressive control of airflow, stopping the flow completely when the button is released.

A smooth backplate with a dozen or so ammonite-shaped holes provides protection against uncomfortable pressure loads on the chest and prevents cold air blasts from penetrating underclothing.

The ergonomic design of the T-VALVE is carefully thought out to provide optimal comfort of use. Its structural reliability ensures progressive and smooth gas flow, allowing for safe operation in any conditions. It’s designed for years of trouble-free use.

The T-Valve is backed by our extended 3-year warranty.

Every piece we create is designed and manufactured in its entirety by Ammonite System in Poland, and the T-Valve is no different.

Each one is also assembled with care by our very own team of professionals, and you can count on our full support from day one.

The T-VALVE can be easily installed and removed without the use of additional tools. However, to make life even easier for users and simplify the (dis)mounting process, we include a steel wrench with each thermo valve.

The stem of the A360 T-VALVE thermo valve has a diameter of 38mm and S360 T-Valve - 33mm.

They are adapted for mounting in drysuits that are prepared for inflation valves in the APEKS (A360 T-VALVE) or SI-TECH (S360 T-VALVE) standard.

Since we only have one habitable planet, everyone has to play a part in protecting the environment.

At Ammonite System, we are deeply committed to preserving the environment, and we’re doing our part.

When selecting boxes, bags, or containers, we have chosen to use recyclable cardboard packaging instead of plastic.

Recyclable packaging is an excellent way to extend the life of previously used materials and positively impact sustainability.
