Axisymmetrical control valves

Axisymmetrical control valves are designed to control the flow rate and pressure of natural, petroleum, and artificial hydrocarbon gases.

These valves are used on process pipelines; process pipings of compressor stations, booster compressor stations, and underground gas storage facilities; sections of gas pipelines from gas production, generation, and storage sites; as well as for oil and oil products transportation.


General characteristics

The valves are manufactured in accordance with TU 3742-044-384383360-2014, TU 3742-045-38438360-2015, and TU28.14.11-052-38438360-2019 for operation at gas production and transportation facilities.

Among the design features of the valves, we can mention high capacity, wide range and accuracy of adjustment, low noise and vibration.
