Live Online Training
Live Online Training combines the advantages of online and face-to-face trainings. It is streamed from the LESER Chatroom and performed according to the same standards as the face-to-face training. No matter from which location you participate - in the office, in the home office or in the workshop, in the practical part you even work on the safety valve yourself.


  • LESER will send you a training box with a LESER API safety valve. In the practical part of the training, you will learn about the individual parts, the design and the function of the safety valve
  • The trainer guides you live through all steps of a calculation and design to the "right" safety valve
  • The communication between the participants is ensured by a fixed number of participants. During the training you are connected live with our trainers and other participants, you can ask questions and share information with each other
  • With successful final examination you will receive a certificate

Be excited about our workshop together with the LESER Training Box.
