The right valve for every application

All DIENES valves are manufactured using optimized production processes and under constant quality control. Design and execution are created in close cooperation with our customers in order to achieve the best possible functional behaviour of the entire compressor for the customer-specific application and to continuously improve the products.

DIENES valves of the Dicron brand are manufactured using the decades of experience of the DIENES plants founded in 1913. Depending on the requirements, our valves are made of standard materials, acid- or corrosion-resistant steel, plastics or various alloys. As a single valve, or as a concentric valve in suction-pressure combination, they always impress with the greatest possible precision with stable safety in every production process.

Numerous market-leading manufacturers around the world trust DIENES valves. They value us not only as a reliable supplier, but also as an innovative development partner. Thanks to our in-house development department and a high level of technical expertise from many years of experience, we offer our customers a wide range of standard products and are also available to assist them with special solutions manufactured individually or in small batches or for special requirements and new machines.

For the benefit of our customers, we have specialized in three areas:

  • Working valves for reciprocating compressors, which include various plate valves, reed valves and strip valves
  • Control components for rotary compressors comprising suction-side, pressure-side and control-side components
