The ball valve seals were examined in strict compliance with DIN EN 1797 and ISO 21010, and clear conditions for safe use were defined during this process. This means that GEMÜ BB02, B22, B42 and B52 ball valves are suitable for the use of gaseous oxygen provided the operating temperature does not exceed 60°C and the maximum operating pressure is 30 bar. PTFE seals and O-rings made from fluorinated rubber (FKM) are used as the seal materials. GEMÜ customers can order the special "O" version of the ball valves for use with oxygen.
BAM emphasised the need for particular caution when handling oxygen. Because of this, all media wetted components in the ball valves for use with oxygen are carefully cleaned. Both the seal materials and the auxiliary materials such as lubricants and screw locking agents comply with the strict regulations.
With these ball valves, valve specialist GEMÜ can now offer another safe solution for handling oxygen. The result of the BAM examination confirms the quality and reliability, and demonstrates the company's commitment to customer safety.
