LESER has a quality management system that accompanies all phases of a safety valve's product development--and it does so worldwide. This is because our "quality cluster" includes all of our locations. LESER works at all sites according to one Global Quality Manual and globally uniform processes so that the same quality standards apply everywhere. Every LESER safety valve therefore has the same quality.

This quality management system is certified according to, among others:

• EN ISO 9001
• Pressure Equipment Directive (PED) 2014/68/EU and EN ISO 4126-1
• ASME XIII
• AQSIQ
