Ball valves for oxygen applications
Oxygen in technical processes has the potential to be extremely dangerous.
The adiabatic compression that may occur when a valve is closed or opened in an uncontrolled manner or just the presence of compressed oxygen alone can lead to a combustion reaction.
This is relevant in particular to non-metallic material such as seals or lubricants. Modified Hy-Lok valves for use with compressed oxygen are available to reduce this type of risk for people and equipment. These valves have been approved by a Notified Body.
