Production Program

The extensive production programme includes:

  • floating ball valves straight and three-way (four-way) ranging from DN 10 to DN 250, up to pressure PN 250 with flanged end, butt weld, socket weld, and screwed connections according to European and international standards ČSN, EN, ISO, DIN
  • floating ball valves straight and three-way (four-way) ranging from NPS 3/8″ to NPS 10″, up to pressure Class 1500 with flanged end, butt weld, socket weld, and screwed connections according to American and British standards API, BS
  • vertical lift-type check valves ranging from DN 50 to DN 400, up to PN 400 in the direct implementation, with a branch, and as an automatic recirculation valves.

We specialize in all kinds of adaptations of ball valves, for example, double ball valves, heating jackets, lockable handles, underground sets, stem extensions, limit switches, different mounting dimensions and end-to-end lengths, metal seated valves, cryogenic valves, etc. All of offered valves are of our own design and manufacture.

Research and Development

The company has its own research and development department, whose staff use modern engineering tools, especially parametric 3D modelling applications, applications for the structural analysis with the finite element method, mathematical calculation programs, and applications for the simulation of fluid flow. All of these applications deliver comfort, accuracy and efficiency in development of our products and considerably contribute to increasing of the quality, reliability, durability and safety. A constant access to the norms and standards relating to industrial valves is a matter of course.


 The primary goal of the company is a satisfied customer who will receive his goods or services in time and in perfect quality. Therefore the company has been applying a quality management system according to EN ISO 9001 since 2004, which is being regularly tested, thus demonstrating the ability to meet customer requirements and achieve high quality products and services.

The company owns a complex of certificates required for the development, manufacture, export and service of valves in harsh operating conditions in the domestic and foreign markets:

  • Quality Management System EN ISO 9001
  • Declaration of Conformity with PED 2014/68/EU (CE marking)
  • Fire resistance approval according to ČSN EN ISO 10497 (API 607)
  • Certificate ATEX (Ex) for potentially explosive atmospheres according to EN 13463–1
  • Certificate for use of valves with Oxygen
  • Certificates for the Eurasian Customs Union – ЕАС (Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russian Federation) - TR CU 010/2011 + TR CU 012/2011 + TR CU 032/2013
  • Certificate SIL 2 – Safety Integrity Level of technical system
  • Certificate of Russian Maritime Register of Shipping

We provide inspection and identification certificate according to EN 10204 3.1 to all of our products.

Production and Inspection

Manufacture and assembly of industrial valves are done by experienced staff at our plant in Opava, Czech Republic. Parts of valves are being measured with regularly calibrated gauges to ensure high accuracy of production, all valves are subjected to shell strength tests and tightness tests on a modern test bench with a digital output.

Main production program consists of:

  • floating ball valves
  • vertical lift-type check valves

Our specialities are ball valves for high temperatures up to +500 °C, cryogenic ball valves, double ball valves, ball valves with heating jacket, ball valves with metal seats (tempered, bronze, Nitronic, Stellite), three-way and four-way ball valves, ball valves for fluids with hydrogen sulfide (H2S), and also ball valves designed according to TA-Luft or EN 15848–1 (fugitive emissions), etc.

We produce valves according to customer's re­quirements with a variety of modifications – lockable control, limit switches, extension of control above insulation of pipeline etc. Forged or rolled raw materials are used for pressure containing parts.

We are a flexible company with creative technical and sales department, which is able to offer customers solutions with short delivery times. Our products have a high technical level based on years of experience of our staff.

Processes within the company subject to a quality management system according to ISO 9001 standards.

All products are designed, manufactured and tested in the Czech Republic.
