Control Valves

Control Valves

Control valves are used in process systems to decrease the pressure in liquid medium production and specifically limit volume flows. 

KIESELMANN offers a wide range of control valves for this purpose. The choice of the appropriate valve depends on its application area. Butterfly control valves, which take up less space and have low cost, are suitable for simple control functions. For processes that require high-level control sensitivity, KI-DS-based single seat control valves are good choices.
