Iċċekkja Valv
Użati biex jipprevjenu l-fluss b'lura, dawn il-valvi huma tipikament attivati waħedhom u jippermettu li l-valv jinfetaħ awtomatikament meta l-midja tgħaddi mill-valv fid-direzzjoni maħsuba u tagħlaq għandha tgħaddi b'lura. Valv, Valv tal-Iċċekkjar tat-truf tal-ħajt, Valv tal-Iċċekkjar tal-Pjanċa Doppja, u Valv tal-Iċċekkjar tal-flanġ, eċċ.
