Regulator "STAR"

Regulator "STAR"
The next step in development of control and anti-surge equipment for pipeline transport.
We have created it with consideration for most demanding requirements in the industry sector.
Gazprom Organization Standard 2–4.1–212–2008:
The 'STAR' regulator features completely new operational characteristics. Primarily, its flow path geometry maintains consistent flow direction throughout the entire regulation zone, solving existing problems through symmetrical central throttling of the flow area.

Schematic cross-section of movable and fixed throttling elements (TE): a) fully open position; b) flow area adjustment. The diagram demonstrates another fundamental advantage — complete absence of central flow path obstructions. Another critical design feature is maintaining constant flow area throughout the entire path. The diagram shows a D=200mm regulator's flow section.

The symmetric central throttling method resolves all major operational challenges: 99% pipeline capacity utilization; perfect flow axial symmetry throughout regulation range; elimination of flow direction changes. We've implemented the 'smooth pipe' principle in flow regulation for the first time, resulting in exponential reduction of compensation costs. This creates substantially more efficient, economical and predictable regulation. The throttling element positioning methodology enables extremely precise adjustment through simple means, preserving gas kinetic energy from compressor stations or wellhead pressure. Maintaining gas flow kinetic energy that would otherwise be lost to regulator design limitations leads to directly proportional operational cost reductions — substantial savings impacting transportation budgets.
Performance Specifications
The valve’s key performance metric is its flow coefficient, which is 1.5 to 3 times higher than that of comparable equipment from other manufacturers.
Energy Efficiency
The valve’s axisymmetric flow path limits energy loss to about 5%, compared with losses of over 60% in cage-guided valves.
Heating Function
These are the world’s first control valves with an integrated heating feature — a critical advantage for reliable operation in low-temperature environments.
Bidirectional Flow
The only control valves that allow gas, steam, or liquid to flow in either direction with no change in performance.
Self-Cleaning Design
The valve’s design resists abrasion from sand, welding slag, and other particles, extending maintenance intervals to up to twice those of standard regulators.
Easy Maintenance
Our regulators can be serviced without removal from the pipeline, with turnaround ranging from just a few hours to a few days. Competing equipment often requires factory repair that can take up to six months.
