Since 1974, when LEUSCH GmbH was founded as a service company to repair and sell monitoring systems in the field of instrumentation and controls, it has developed to become a leading manufacturer of first-rate industrial valves.

Already in 1985, Jacob Leusch, founder and chief executive officer of Leusch GmbH, used the experience he had gained to design and manufacture standard valves as well as high-pressure valves made of special materials. Within a short time, the company had established itself on the international market with the development of mainly ball valves, segmented ball valves as well as control and shut-off butterfly valves for temperature ranges from –196 to +1000 °C, in pressure ratings up to PN 420 or Class 2500 and in a wide variety of materials.

LEUSCH joined forces with SAMSON in 2003. Today, valves by LEUSCH are used in many sectors of industry.

Our promise

Quality is our tradition. To meet the high quality requirements placed on our products, our construction and production are based on the ISO 9001:2015, HP 0/TRD 201 quality management systems as well as on international standards, such as the European Pressure Equipment Directive 2014/68/EU. All valves leaving our works have been subjected to a 100 % leak, function and quality testing procedure. Thanks to production planning and scheduling, customers know the manufacturing and testing status of their valves at any time.

As a modern manufacturer, SAMSON LEUSCH stands for sustainability and continuity. We use our commitment and technical expertise to achieve the highest level of safety, reliability and durability with our control and shut-off butterfly valves. Every control valve that we make is the result of decade-long experience, continuous development and compliance with the strictest standards.
