The paper presents the results of the numerical study of the flow in a symmetric model of the venous valve with different leaflet elasticity. The focus is on the analysis of the velocity field and the stagnant region. The stagnant region behind the valve is of great practical interest for phlebologists in terms of the potential for the formation of blood clots. The constructed simplified model of the venous valve has given a good qualitative agreement with the clinical ultrasound data on the position of the valve leaflet and the stagnant zone behind the valve.
