Qaybaha shubka ee Valve iyo Pump

Qaybaha waalka tuurista,bir aan lahayniyo ductile (spheroidal graphite) kabka birta ah waa laba ka mid ah alloys aadka loo isticmaalo sababtoo ahDucitle cast ironwaxay leeyihiin waxqabadka ka hortagga miridhku ka fiican yahay iyo birta aan la taaban karin waxay leeyihiin waxqabad fiican ee caabbinta kulaylka iyo iska caabinta daxalka. Waxaa loo isticmaalaa soo saarista:

• Balanbaalista iyo Baallaha Kubbada (Birta Ductile Cast ama Birta Aan-Aamaha lahayn),
• Saxanadaha Valve Balanbaalista (Staelless Steel ama Birta Ductile),
• Kuraasta Valve (Birta shubka ah ama birta ah ee shubka ah)
• Bambooyinka Centrifugal iyo Daboolka (SS ama Birta Ductile)
• Bambooyinka Impellers iyo Daboolka (Birta Aan-Aabaha lahayn, Birta Aan Lahayn ee Duplex)
• Guryaha Bambada Sita ( Birta Cawlan ama Birta Daawaha ah)
