A lockable flap allows you to close down entry pipes to inspection chambers to allow essential maintenance to be carried out. Review: Anche se il prezzo è decisamente elevato, la valvola si presenta con materiali di ottima qualità e la fattura del prodotto è molto elevata. Il prezzo vale l'acquisto poiché è l'unica che può essere installata infilandola direttamente all'interno del tubo, perfetta in quei casi non si ha uno spezzone di tubo atto a fare da maschio con le altre valvole di non ritorno.
