One-way vent valves play a crucial role during open-heart surgery by redirecting blood from the heart to a heart-lung machine. The duckbill valve must prevent reverse flow and airflow back to the ...

A leaky heart valve makes blood flow backwards. Many people live unaware of this condition. It can strain the heart and cause ...

The stopcock is designed for applications requiring a one-way flow and easy on and off capabilities; flow is changed by rotating the unidirectional handle 90° in either direction.

The aortic valve controls the one-way flow of blood from the left ventricle (chamber) of the heart to the aorta. The aorta is the main artery responsible for delivering blood to the rest of the body.

vpdd = Δp (qmax) Δp (qmin) where: vpdd=valve pressure drop decay Δp (qmax)=valve pressure drop at maximun flow Δp (qmin)=valve pressure drop at minimun flow Using the vpdd calculation, the control ...
