New control valves for European gas pipeline

Bath, UK – Ukrainian energy company Ukrgaz Energo is employing advanced valve actuators as part of an upgrade programme on the pipeline network connecting Russia and Central Asia with Western Europe.

Ukraine is an important part of this energy supply infrastructure which, in total, meets one third of Western Europe’s demand for natural gas. The country handles around 90% of the gas supplied by Gazprom in Russia.

In a recently completed project, Ukrgaz Energo installed 28 Rotork CVA modulating electric valve actuators on the compressor station at Bilche-Volytsa, replacing obsolete pneumatic equipment.

The package consisting of linear output actuators and new globe valves to improve diethylenglycol (DEG) control on the station’s dehumidification unit. Assembly, test and calibration of the actuators and valves was performed at Ukrainian distributor ITO’s factory.

The actuators are designed to deliver continuous, repeatable modulating control with a programmable fail to position option. Resolution, repeatability and hysteresis performance is quoted at less than 0.1% of full scale, offering suitability for the most demanding control valve applications.
