Ammonite Thermovalve T360

Ammonite 360 T-Valve for Heated Suit Systems

Ammonite 360 T-VALVE can rotate a total of 360 degrees allowing for a wide range of hose configurations thus, it truly doesn't matter in this case if one rig routes the drysuit hose under the right arm and another under the left.

Highest quality coaxial E/O cable

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

Higher performance, lower profile

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.

Supreme quality construction

The thermo valve is robust due to its nickle plated brass and stainless steel parts. The carefully designed structure contributes to the reduction of the wear of the seals and general exceptional durability.

Progressive and smooth air management

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

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

Ergonomic design

T-VALVE ergonomic design is thought-out in such a way that it provides top comfort of use. Its constructional reliability ensures progressive and smooth gas flow along with safe exploitation in any conditions. It's designed for years and years of trouble-free use.

3-years warranty

T-Valve is backed by our extended to 3 years warranty.

Genuine AMMONITE SYSTEM construction

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.

Convenient mounting and dismounting

T-VALVE can be easily installed and removed without the use of additional tools. But to make its users' life even easier and simplify the (dis)mounting process, we add a steel wrench to each thermo valve.

Available in both APEKS and SI TECH standards

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.

Eco friendly packaging

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

As part of Ammonite's ongoing commitment to the enviornment, when deciding on boxes, bags, or containers, they have chosen to use recyclable cardboard packaging instead of plastic.

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