Definition / notes:	Imagine vana glisanta: http://www.commaz.ro/vane.html Imagine knife gate valve: http://www.webpanel.co.uk/catalogue/images/albion_3614p1.jpg In dictionarul tehnic "gate valve" apare ca "vana glisanta". Eu am adaugat cu cutit pentru ca reiese din imagini. Am gasit si "vana cutit" ca termen, dar as zice ca e o combinatie intre cele doua.
