Valve ya kusimamisha ina utendaji mzuri wa udhibiti, utendakazi duni wa kuziba, muundo rahisi, utengenezaji na matengenezo rahisi, upinzani mkubwa wa maji na bei ya bei nafuu kuliko vali ya lango.
Vigezo vya uteuzi:
Vipu vya kuacha vinapaswa kuchaguliwa kwenye mabomba au vifaa vilivyo na joto la juu na vyombo vya habari vya shinikizo la juu;Kwa mfano, valves za kuacha zinapaswa kuchaguliwa kwa joto la juu na mabomba ya shinikizo la juu ya mimea ya nguvu ya joto na mifumo ya petrochemical;
Ambapo upinzani wa convection kwenye bomba sio kali, yaani, ambapo hasara ya shinikizo haizingatiwi;
Vipu vya kuacha vinaweza kuchaguliwa kwa valves ndogo, kama vile valve ya sindano, valve ya chombo, valve ya sampuli, valve ya kupima shinikizo, nk;
