EMET 'Step-Vane' and 'Swing-Through-Vane' Butterfly Control Valves have been designed and developed for applications where leakage in the closed position is not the problem, but the control of the amount of liquid or gas through the pipe line is paramount. These valves provide excellent throttling performance.

Series 40500 and 40600 Butterfly Control Valves (with Anti-Cavitation/Low Noise Trim) have been designed and developed by EMET Controls to use in process engineering and industrial applications where the effect of cavitation (due to high liquid pressure drop) cannot be eliminated/handled by Series 40000 and 40100 Butterfly Control Valves.
