Kuna udhibiti wa mtiririko au udhibiti wa shinikizo, lakini usahihi wa udhibiti sio juu, na kipenyo cha bomba ni kidogo.Kwa mfano, kwenye bomba yenye kipenyo cha kawaida ≤ 50mm, valve ya kuacha au valve ya koo inapaswa kuchaguliwa;
Kwa ajili ya miradi ya ugavi wa maji na inapokanzwa katika ujenzi wa mijini, ikiwa kipenyo cha kawaida ni kidogo, valve ya kuacha, valve ya usawa au valve ya plunger inaweza kuchaguliwa, kama vile kwenye bomba na kipenyo cha kawaida chini ya 150mm;
Inatumika kwa mvuke na mabomba mengine ya kati chini ya DN200;
Siofaa kwa kati na viscosity ya juu;
Haitumiki kwa midia iliyo na chembe ambazo ni rahisi kunyesha;
Haipaswi kutumika kama valve ya vent na valve ya mfumo wa utupu wa chini.
Kawaida:
