control of steam turbine valves is relatively new, beginning around 2002. These are different from the electric actuators used with gas turbines and pilot valve actuation of steam turbines, as this application requires an order of magnitude higher force and works under considerably more challenging conditions. buy nema sm 24 : 1991(r2002) land based steam turbine generator sets 0 to 33,000 kw from sai global
