Abstract: Experiments were run on a poppet valve operating in hydraulic oil. The experimental values of the flow forces and discharge coefficients were about 25 per cent below the predicted theoretical values. Although there was some scatter in the values of discharge coefficients, there was good correlation for the flow forces. Flow forces are strongly influenced by the downstream configuration. The smaller the diameter of the downstream chamber, the higher the forces. A poppet configuration was designed and tested which virtually eliminated the flow forces.
