History and Present

POLNA corp. s.r.o. based in the town of Třinec – an important town in the Moravian-Silesian region with a long tradition in the metallurgical industry surrounded by the beautiful Beskydy Mountains.

Since the beginning of its existence, the company has been engaged in the design, calculation, production and supply of industrial valves.

In 2004, in order to improve the comprehensibility of the design of control valves for our customers, we created our own computer program DiVENT.

In 2008, the production program was expanded to include equipment for adjusting steam parameters as part of the company’s development. Since 2013, we have also been dealing with the production and supply of control valves that meet even the strictest requirements of nuclear power plants.

One of our strong points is our own research, development and implementation of new technical solutions. For example, in 2017 (based on the individual requirements of our key customers) in cooperation with VSB – Technical University of Ostrava, we developed a new desuperheater design with increased steam cooling efficiency. Two years later, we developed a new type of desuperheater using atomizing steam. We are constantly developing new design solutions for control valves that adapt to increasingly demanding conditions, especially in the energy industry.

With our expanding product portfolio and development activities, we decided to build new company bramch, which also include a development and testing center. In the first half of 2020, the company moved to new premises in Třinec.

Our products are currently exported almost all over the world – under the POLNA brand.
