flapper valve

A type of valve that permits the flow of fluids in one direction only.
When the fluid moves from the “In” side, the piston moves from right to left and the fluid goes through the holes in the piston. When fluid moves from the “Out” side, the piston moves from left to the right under spring pressure and closes the “In” port preventing flow of fluid in the reverse direction.
