Valves for process gas applications in the chemical industry

For applications in the chemical industry or in petrochemical plants, DIENES offers long-proven valves according to special specifications. These valves with special quality features are designed and manufactured according to the current standards and regulations tailored to the respective application. National/international standards such as API / NACE / DIN EN ISO 15156 are applied here.

    The various DIENES high-performance valves can be used for chemical / petrochemical processes.

    Depending on the operating medium, the selected valves can be equipped with steel or adapted plastic valve plates.

    Due to the special requirements of highly corrosive media, however, valves of the GS-K series are mainly used here.

    It goes without saying that the design is precisely tailored to the application specified by the customer in order to ensure maximum performance coupled with optimum operational reliability and service life.
    By means of our own design programs, all DIENES process gas valves are optimized for the respective application. In order to achieve maximum running times, plate movement and impact velocities are carefully checked and the results communicated to the customer.

  • Check valves for the petrochemical industry

    Check valves for the petrochemical industry

    Automatic closing check valves are usually required to protect the compressor units from the supply network.

    These check valves can be realized with a variety of DIENES standard valves.

    The selection and design of the check valves is process-oriented and in accordance with the design standards suitable for the application.

    Steel plate valves are generally used here, depending on the application and customer specifications as individual valves for direct installation in customer housings or as a complete assembly with housing for installation in any pipeline.

    By means of our own design programs, all DIENES check valves are performance-optimized for the respective application.


  • Control components

    Control components

    The task of a compressor control system is to adapt the flow rate as precisely as possible to the changing withdrawal or accumulating quantity, because it is obvious that economical operation can only be guaranteed if only the actually required gas quantity is compressed at any one time.

    Furthermore, in many quantities the control system must still guarantee that the compressor is not or only slightly loaded when the machine set is started up, i.e. that it can be switched to complete idling.

    Thanks to the regulation devices developed by DIENES and specially designed for each application, our engineers are able to solve the tasks described above in an optimal way for all types of compressors and all possible applications.

    Available components:

    • Lift-off systems for all types of suction valves used
    • Actuators for actuation of the lift-off systems
    • Intermittent duty regulators for use with cylinder shutdowns
    • Pressure ratio controllers for use with pneumatic back pressure controls
