Smart, Simple, Unique

SMARTOP™ is our smart and unique residual pressure valve that simplifies gas handling and improves safety.


SMARTOP: a safe, convenient and innovative cylinder valve from Air Liquide for specialty gases

Our SMARTOP™ is equipped with an on/off lever and a permanent pressure gauge, allowing you to check the content of your cylinder anytime. Visual ID of the valve status also prevents valves from being left open during breaks and off-business hours.

Packaged gas cylinders with SMARTOP™ valves also come with an ergonomic open cap that allows customers to safely and quickly move and handle compressed gas cylinders with greater ease. This open cap also eliminates the need to remove or replace cylinder caps.

SMARTOP™ is available with our ALPHAGAZ™ brand specialty pure gases.
