Precision Under Control - STL Introduces the Aeroflow Valve

STL Power & Process Controls Ltd work in partnership with Armstrong International’s Flow Control Group – formerly Leslie Controls – to offer its Aeroflow severe-service valve, engineered to perform where failure is not an option.

Modern power generation and industrial processing facilities continue to push equipment to its limits, driving demand for control valves that maintain accuracy and stability under extreme operating conditions. 

Engineered for Demanding Service Conditions

These valves are purpose‑built for high‑pressure, high‑temperature, and high‑turbulence service - conditions typical of feedwater, steam conditioning, turbine bypass, and industrial process loops.  Their aerodynamic/hydrodynamic design improves Cv‑to‑body‑size ratios whilst minimising turbulence and noise, two critical parameters for operators running tightly controlled thermal or power systems.

A modular architecture allows application‑specific trim configurations without increasing cost or lead times.  This is especially advantageous for engineering firms seeking performance customisation without procurement complexity.

Zero‑Leakage Shutoff for Critical Isolation

A defining feature of the design is its pressure‑energized, pilot‑balanced plug assembly, engineered to deliver true zero‑leakage shutoff - surpassing ANSI Class VI performance expectations.

By eliminating piston seals, the design reduces wear points and extends operational life, whilst field‑interchangeable trim modules simplify overhaul planning and lower lifecycle maintenance costs.

Configurable Solutions for Complex Industrial Systems

Every facility presents unique piping geometries, load profiles, and control challenges.  Aeroflow’s highly configurable options allow specifiers to match valve characteristics precisely to system requirements.  In many cases, a single Aeroflow valve from STL can replace multiple conventional valves, reducing system complexity, streamlining maintenance, and improving operational efficiency.

Across power, industrial, and energy facilities worldwide, Aeroflow valves routinely demonstrate improved uptime, reduced acoustic emissions, superior control stability, and lower total cost of ownership.
