LESER Quality and Environmental Management

Safety valves protect our customers’ products and plants and therewith prevent injury or damage to people and the environment. They are the last link in the safety chain and must function when the situation requires them to. LESER claims that we guarantee this protection. For this reason we have a Quality Management System (QMS) installed that accompanies all phases of product creation. The QMS is certified according to


  • EN ISO 9001
  • Pressure Equipment Directive (PED) 97/23/EC resp. 2014/68/EU and EN ISO 4126-1
  • and other standards.

It begins in the development phase of a new product and ends with its environmentally correct disposal. All LESER employees work to ensure that standards are met and enforced in their workplaces. This applies worldwide, also to our subsidiaries and the sales and service partners.

Besides the high standards we ourselves set for our products, our actions are based on requirements set by standards and regulations and our customers’ own individual requirements. In this way LESER uses the absolute highest standards as its gauge. The obtaining and maintaining of worldwide licensing and certifications reflects this commitment.

Environmental questions play a significant role in planning and implementing activities for our processes in the areas of material management and the manufacture of LESER products. Appropriately considering effects on the environment is decisive to the nature and extent of these activities. Through the use of numerous environmental protection programs, effects on the environment can be kept to a minimum. Our efforts to become even more environmentally friendly in the future drive us to apply the necessary diligence when selecting suitable operating resources. Maintaining certification according to EN ISO 14001 sets the necessary framework for these efforts.
