there r two valves: aortic semilunar valve and pulmonary semilunar valve

pulmonary semilunar valve

No. in my opinion, Chordae tendineae is attached to Tricuspid valve and bicuspid valve. Both valves do not have semilunar valves. Pulmonary valve and Aortic valve has semilunar valve.

Blood leaving the the right ventricle through the pulmonary semilunar valve moves toward the lungs. Blood leaving the left ventricle though the aortic semilunar valve moves toward every where but the lungs.

The AV valve is open and the semilunar valve is closed during ventricular diastole.
