Valvula Retinenda
Ad refluxum prohibendum adhibitae, hae valvae typice se ipsae activantur, permittens valvam sponte aperiri cum medium per valvam in directione destinata transit et claudi si fluit retrorsum. Inter quas sunt valvae anti-retroactivae oscillantes non-reditus, valvae anti-retroactivae ferreae, valvae anti-retroactivae undulae, valvae anti-retroactivae cum extremitatibus filetatis, valvae anti-retroactivae duplici lamina, et valvae anti-retroactivae cum flange, et cetera.
