Singase sivame ukubona ezinye izinhlamvu noma izinombolo emzimbeni we-valve, futhi abangani abangayazi i-valve bangase badidwe yilezi zinhlamvu nezinombolo.Uma nje ufunda isikhashana, uzothola lezi zinhlamvu nezinombolo ziwusizo kakhulu.

Isibonelo, emzimbeni we-valve yensimbi engenasici, amagama athi CF8 / CF8M avame ukubonakala.Lawa magama amele ukwakheka kwe-valve yomzimba.I-CF8 / CF8M izindinganiso zaseMelika.Amakhodi abo ensimbi asekhaya ahambisanayo ayinsimbi engagqwali engu-304 kanye nensimbi engagqwali engu-316, kanye.Uhulumeni waseShayina udinga ukuthi i-valve body material (efana ne-CF8 / CF8M), i-diameter yegama (efana ne-DN150 DN60), ingcindezi yamagama (efana ne-PN16, PN40), inombolo yesithando somlilo (efana no-7538), njll., ilingane ekunikezeni abasebenzisi ulwazi lwepharamitha ye-valve kanye nobufakazi bobunikazi, okusiza abasebenzisi bakwazi kangcono ukusetshenziswa kwamavalvu.
