Clear knowledge on the thrust of valves is necessary to discuss the stability of valves which plays an important role concerning the stability of a pipe line. In order to have a general idea of relations between the thrust and the lift, and between the discharge coefficient and the lift of common valves, we studied the characteristics of the most simplified valve, that is, a circular disc valve. The flow between the valve and the valve seat is very complex. The pressure distribution over the valve surface and the lifting-force were calculated analytically for various types of the flow, and examined experimentally for three kinds of disc valve. Experimental results show the correlation between the lifting-force and the discharge coefficient.
