• This paper deals with the free jet issuing from the metering orifice of a seat type two-way-cartridge valve. In order to estimate the flow force acting on the valve exactly, it is important to know the jet angle and the jet width from the metering orifice in the valve. The flow pattern of the free jet was analysed using conformal mapping, where the flow was assumed nonviscous. From this analysis the relations among the jet angle, the jet width, the lift of the valve piston and the angle between the valve piston and the valve seat were obtained. Experiments were conducted to visualize the flow inside the two-way-cartridge valve. Then, to make the effect of viscosity clear, the flow pattern was numerically calculated using a streamline coordinate system, where the flow was assumed viscous. The theoretical results agreed very well with the experimental ones.
