Iindlela zangoku: Iivalvu zebhola ezisekelwe kubukhulu (ubuninzi be-intshi eyi-1, i-intshi eyi-1 - i-intshi ezi-6, i-intshi ezi-6 ukuya kwii-intshi ezingama-25, i-intshi ezingama-25 ukuya kwii-intshi ezingama-50, ii-intshi ezingama-50 nangaphezulu), uhlobo (intaba ye-trunnion, edadayo, ipali), iMakethe yezinto eziphathekayo ( intsimbi engatyiwa, intsimbi, ingxubevange, ubushushu obuphantsi)

Ukusukela ngo-2019 ukuya ku-2024, imakethi yevalvu yebhola kulindeleke ukuba ikhule ngesantya sokukhula sonyaka esisi-3.75%. Ngo-2024, iya kukhula ukusuka kwi-12.6 yeebhiliyoni zeedola zaseMelika ngo-2019 ukuya kwi-15.2 yeebhiliyoni zeedola.
Ukwahlulwe ngokobukhulu, imarike yevalve yebhola yahlulwe yaba yi-intshi enkulu eyi-1, i-intshi e-1 ukuya kwi-intshi ezi-6, i-intshi ezi-6 ukuya kwi-intshi ezingama-25, i-intshi ezingama-25 ukuya kwii-intshi ezingama-50, kunye ne-intshi ezingama-50 kunye neemarike ezinkulu. Ngexesha loqikelelo, imakethi yevalve yebhola esekwe ku-1 ″ ukuya kwi-6 ″ kulindeleke ukuba ibone ukukhula okubonakalayo. Oku kukhula kubalelwa kukwanda kwemfuno yezothutho namandla kunye nezicelo ezisekelwe kumbane; ngenxa yoko, ukusetyenziswa kwe-intshi ye-1-6 i-valve kwi-oyile kunye negesi, amandla kunye namandla, ukucocwa kwamanzi kunye namanzi amdaka, iikhemikhali kunye namanye amashishini Kuye kwanda.
Kule ngxelo, imakethi yevalve yebhola yahlulwe yaba ziivalve ezixhonywe kwi-trunnion, ezidadayo kunye neziqu ezithe nkqo ngohlobo lwevalvu. Phakathi kwabo, kulindeleke ukuba i-trunnion efakiweyo ithathe esona sabelo sikhulu sentengiso kulo lonke ixesha loqikelelo. Ukukhula kokusetyenziswa kwamandla, ubugcisa obutsha bemveliso, imfuno yokhuseleko lwenkqubo, ukonyusa ingqwalasela yokuzinza, kunye nokukhuthazwa kwemithetho yendalo esingqongileyo kukhuthaze uphuhliso lwemarike yevalve yebhola yetrunnion.
Ingxelo yaphula imarike yevalve yebhola ngezinto, uhlobo lwevalvu, ubungakanani, ishishini kunye nendawo. Ingxelo ikwachaza abaqhubi abaphambili, imiqobo, imingeni kunye namathuba anxulumene nemarike, kunye nekhonkco lexabiso kunye nohlalutyo lwenqanaba lemarike.
