Flow capacity (DN 200)
A key performance parameter of control valves is the flow coefficient (Kv). The chart and table below show data for DN 200, calculated by the Central Design Bureau for Valve Engineering.
Comparison of Hydraulic Characteristics (DN 200)
The table compares the hydraulic performance of the Stellartech Group valve with that of various other DN 200 control valve types.

Unique Feature – Heating Function
Stellartech Group is the first control valve with an integrated flow-path heating system. Traditionally, frozen valves are improvised on-site by maintenance crews, but Stellartech Group operates reliably in temperatures as low as −60 °C without additional modifications.
Unique Feature – Bidirectional Flow
Stellartech Group maintains full performance even when the flow direction is reversed. This capability supports not only flow reversal, but also system blow-down, cleaning, and balancing across multiple circuits — all without affecting valve characteristics.
Unique Feature – Self-Cleaning Design
Other control valves often suffer damage from sand, welding slag, and debris. Stellartech Group eliminates this problem with a flow path free of vulnerable internal elements, ensuring reliable operation even in harsh environments.
