Ammonite T-Valve


Secure and adjustable
It’s a high-performance, low-profile 360-degree swivel drysuit Inflation Thermo Valve made
with superb quality, tried-and-tested components.
Its 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.
Small and convenient, this ultra-low-profile thermo valve can be adapted to any
configuration of BM, SM, and REB.
The A360 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.
Due to proper air dispersion, using the valve is comfortable and intuitive – all without
compromising in reliability and safety.

Solid and reliable
We used a virtually unbreakable E/O cord. 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.
The A360 T-Valve has a very low profile, a streamline construction and features a domed
form. All that transfers to reducing snag hazards, regardless of where the valve is
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
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.

Safe and comfortable
The A360 T-Valve can be easily installed and removed without the use of additional tools.
But to make its users’ life even even easier and simplify the (dis)mounting process, we add
a steel wrench to each thermo valve.
