Your partner for advanced valve technologies

We are a leading company in the development, manufacture and sale of sophisticated valve technologies made of metal and plastic.

SAMON SED relies on 120 highly skilled employees to develop and manufacture custom-made metal diaphragm valves for aseptic service as well as metal and plastic diaphragm and angle seat valves for industrial applications. The product range also includes positioners, valve monitoring and control units, solenoid valves and flow meters.
SED's strengths lie in its flexibility, customer proximity and innovative strength. The acquisition by SAMSON gives SED access to a worldwide sales and service network.

SED specializes in the development, manufacture and distribution of diaphragm valves, seat valves and variable area flow meters. In addition, SED offers a wide range of mechanical and electric accesso-ries for monitoring and control that is perfectly tailored to the valves. Valve bodies and actuator components are made of high-quality metals and plastic materials.

No matter what market you serve, you will always find the right product for your application. Starting from basic 2/2 way valves to customized solutions including the monitoring and control equipment.

SED was founded in 1984. Back then, SED laid the foundations for a comprehensive range of attractive products, which – in continually improved versions – still contribute greatly to the success the company has today.

SED joined a group of companies in the mid-1990s, which meant that the company could reorient its business and make important investments for the future. New valves were developed, tailor made for use in pharmaceutical and biotechnology applications. The entire product range was adapted to these target markets. This focusing on specific markets and core competences as well as a thorough reorganization of the sales structures made it possible for SED to successfully establish itself in the new markets.

In 2010, the company moved to new facilities. As part of the relocation, processes and procedures were reorganized and optimized. Thanks to these modifications, SED can meet its customers' demands and achieve consistent profitable growth.

On 7 September 2017, SED became a subsidiary of SAMSON AKTIENGESELLSCHAFT, which is headquartered in Frankfurt am Main, Germany.
Backed by a parent company like SAMSON, SED's presence in all important markets is strengthened, particularly in the life sciences sector. Synergies are also created in terms of digitization. SAMSON is pushing digitized process automation based on smart, networked valve technology.

Our ultimate benchmark for quality is the complete satisfaction of our customers. Only then, may a successful and sustained existence in the market be guaranteed. The prerequisite for quality is, however, not only a matter of functional products. Therefore, SED Flow Control applies its quality concept comprehensively to all areas of business. This includes research and development, production, suppliers, services and our sales team.

The fundamental areas of our quality policy:

By means of personal communication and direct customer input, SED achieves an accelerated implementation of innovation and customized solutions. This aspect finds support by specializing on development and production areas with efficient experience and extensive training requirements.

“My colleague is my customer” is the motto that applies for each individual step of our manufacturing process. This means that everybody handles their production responsibility in a way that satisfies the internal customer and ultimately leads to the best work possible.

Our customer is our employer and should see their visions and wishes realized. Therefore, our policy is to closely cooperate with our customers to develop optimal solutions and implement these solutions with cost effective results.

The quality of our products is directly dependent on the performance of our suppliers. Through a supplier qualification process, continuous assessments are performed, documented and form the basis of a close customer-supplier-relationship.

The greatest asset of our company is our employees. Embracing quality is not the result of individuals but the outcome of successful teamwork. The ability to develop new ideas, to take on responsibility and to show initiative and creativity brings us continuous development and improvement. Each level of the company believes in our quality and growth philosophy and this is reinforced with continued education.

Please note that our jobs are only advertised in German.
