This invention provides a simple, rotary, reliable, compact, anticoagulant, artificial or mechanical heart valve based on two rotary pressure porting mechanisms. This valve provides one center flow stream without any obstruction which only human heart valve can provide so far. It employs about 1/5 of the energy that the conventional mechanical heart valve consumes. This mechanical heart valve includes three basic configurations with one leaflet, two and three leaflets for various human heart valve replacement. This valve has the most reliable designs over all existing mechanical heart valves. The reliable features includes less moving part, dual redundant hinge-actuation system and inclusive designs; either loosing proof or falling out proof. Finally most importantly, the invention is provided with an unique anticoagulant mechanisms which include mechanical and medical methods to clean up clots and prolong life of this valve up to 20-40 years. Above all this valve meets and exceed most performance requirements of human heart valve. These rotary pressure porting mechanisms have vast applications and many advantages over conventional linear or rotary pressure porting mechanisms and applied to check valves, pressure relief valves and pressure regulators or their combinations. They can be employed for many fields including medical devices, aerospace industries, automotives, process controls, food process, chemical plants, oil and refinery, HVAC and others.
