Experimental Verification of Balanced Control Valve

Abstract:

Findings are presented from the tests of balanced control valve mounted on the steam piping with experimental turbine. The forces applied on the spindle are recorded and compared to design calculation. The forces are evaluated from the pressures on a servo drive piston or they are measured directly using force transducers. The real operational characteristics are compared with characteristics defined for constant inlet pressure.
