Makhalidwe a American standard cast steel globe valve

1. Mankhwalawa amapangidwa ndi kupangidwa molingana ndi miyezo ya ASME B16.34 ndi BS, yokhala ndi dongosolo loyenera, kusindikiza kodalirika, ntchito zabwino kwambiri ndi maonekedwe okongola;

2. Malo osindikizira omwe amakutidwa ndi Co based cemented carbide ali ndi kukana kovala bwino, kukana dzimbiri, kukana abrasion ndi moyo wautali wautumiki;

3. Tsinde la valavu lili ndi kukana kwa dzimbiri komanso kukana kukanika pambuyo pozimitsa ndi kutentha ndi chithandizo cha nitriding pamwamba;

4. Mphuno yokhala ndi mphamvu ≥ class1500 imatenga mawonekedwe odzikongoletsera okha, ndipo ntchito yosindikiza imawonjezeka ndi kuwonjezeka kwa mphamvu ya mkati, zomwe zimatsimikizira kudalirika kwa kusindikiza;

5. Vavu ili ndi mawonekedwe osindikizira, omwe ndi odalirika;

6. Zinthu za zigawo ndi kukula kwa matako kuwotcherera mapeto a flange akhoza kusankhidwa moyenerera malinga ndi mmene ntchito zenizeni kapena zofunika wosuta kukwaniritsa zosiyanasiyana uinjiniya zosowa.
