Ayrim armaturalarda klinali zulfin o‘rniga murvat o‘rnatilgan bo‘ladi.
Murvatning zulfinga nisbatan afzalliklari:
1) murvatning tashqi o‘lchami va og‘irligi zulfindan kichik bo‘lib, bu
armaturaning tashqi o‘lchami va og‘irligini kichkina bo‘lishini ta‘minlaydi;
2)
murvatda oqish muhiti, deyarli o‘z yo‘nalishini o‘zgartirmaydi;
3) murvatni ochish – yopish tez amalga oshirilishi bilan.
Bu armaturalar o‘zagidagi o‘chish teshigi diametri 62 mm
va yonidagi teshik
diametri 60 mm.
