About the Principal
Founded in 1818 in Hamburg, Germany, LESER is the largest manufacturer of safety valves in Europe and one of the leading companies in its industry worldwide. LESER specialises exclusively in safety valves — producing over 150,000 units per year at Hohenwestedt, Germany, Europe’s largest safety valve production plant, with additional plants in India and China.
LESER offers spring-loaded and pilot-operated safety valves for all industrial applications in accordance with the Pressure Equipment Directive (PED) and ASME VIII, including the API 526 range.
