Ingcinezelo elawula ukungaphumeleli ngamanye amaxesha kusenzeka ekusebenziseni ivalve egqwesileyo. Kukho izinto ezimbini ze-phenomena yoMthetho wokuLawulwa kwePilot Calve: Enye yeyokuba uxinzelelo alunakumiselwa ngokuhlengahlengiswa kwesandla esilawulayo; Enye indlela kukulungelelanisa uxinzelelo lwesandla ngaphandle kokuwa, okanye ukwandisa uxinzelelo ngokuqhubekayo. Kukho izizathu zokusilela kommiselo woxinzelelo, ngaphandle kwe-radial vill ye-valve ye-valve ngenxa yezizathu ezahlukeneyo:

Okokuqala, i-uperper ye-valve ephambili ye-valve (2) ivaliwe, kwaye uxinzelelo lweoyile alunakudlulisela kwigumbi eliphezulu le-valve ephambili kunye ne-valve ye-pilot ivaliwe yokulawula uxinzelelo lwevalve ephambili. Kuba akukho xinzelelo lwe-oyile kwigumbi eliphezulu le-valve ephambili kunye nomkhosi wasentwasahlobo mncinci kakhulu, ivalve ephambili iba yivalve yoncedo engathethekiyo entwasahlobo. Xa uxinzelelo kwigumbi lokungena kweoyile liphantsi kakhulu, ivalve ephambili ivula ivalve yokunceda kwaye inkqubo ayinakukwazi ukufumana uxinzelelo.

Isizathu sokuba ingcinezelo ayikwazi ukufikelela kwixabiso eliqingqiweyo kukuba uxinzelelo lwentwasahlobo lukhethwe okanye ukwenziwa ngempazamo, okanye i-conve yoxinzelelo yevalve inkulu kakhulu.

Okwesibini, i-uperper (3) ivaliwe, ukuze uxinzelelo lweoyile alunakudlulisela kwivalve ye-cone, kwaye i-pilot valve iphulukana nomsebenzi wokuhlengahlengisa i-valve ephambili. Emva kwe-uperper (i-orifice) ivaliwe, ivalve yeCone ayiyi kuvula ioyile egqobhozayo phantsi kwalo naluphi na uxinzelelo, kwaye akukho Oraing ehamba evaliwe ngalo lonke ixesha. Ingcinezelo kumagumbi aphezulu nangaphantsi aphezulu kwivalve ephambili ahlala elingana. Kuba indawo yokutsala i-annan esiphelweni kwe-van ye-valve ephambili inkulu kakhulu kuneso siphelo, ivalve ephambili ihlala ivaliwe kwaye ayizukugcwala, kwaye i-varity yeva-valve iyonyuka ngokunyuka komthwalo. Xa i-Actortotor iyayeka ukusebenza, uxinzelelo lwenkqubo luyongeza ngokungapheliyo. Ukongeza kwezi zizathu, kusafuneka ukukhangela ukuba ingaba izibuko lolawulo lwangaphandle luvaliwe kwaye nokuba ivalve ifakwe kakuhle.
