Uma unolwazi oluyisisekelo lwe-valve, cishe ujwayelene naloivalvu yebhola– olunye lwezinhlobo ezivame kakhulu zamavalvu atholakalayo namuhla. Ivalvu yebhola ngokuvamile iyivalvu yokujika ngekota enebhola elinezimbobo phakathi ukulawula ukugeleza. Lawa mavalvu aziwa ngokuqina nokuvala okuhle kakhulu, kodwa awahlinzeki njalo ngokulawula okunembile. Ake sixoxe ngokuthi kulungile nini ukusebenzisa ivalvu yebhola njengevalvu yokulawula.
Ngisho noma ama-ball valve engeyona idivayisi engcono kakhulu yokulawula ukugeleza, asasetshenziswa kakhulu ngenxa yokuthi ayabiza kakhulu. Ungaphumelela ngokusebenzisa i-ball valve kuhlelo lokusebenza olungadingi ukulungiswa nokulawulwa okuqondile. Isibonelo, i-ball valve akufanele ibe nenkinga yokugcina ithangi elikhulu ligcwele ezingeni elithile ngaphakathi kwamasentimitha ambalwa.
Njenganoma yimiphi imishini, kuzodingeka ucabangele izimo zenqubo ephelele ngaphambi kokukhetha ivalvu yakho. Lokhu kufaka phakathi umkhiqizo noma impahla, usayizi wamapayipi, izinga lokugeleza, njll. Uma uzama ukulawula impahla ebizayo okhathazekile ngokuyichitha, ungase ungafuni ukuthembela kuvalvu yebhola.
Amavalvu ebhola awaqondile kakhulu ngoba ukulungiswa kwawo akuhambisani nenani elikhulu lokugeleza elinikezwa yimbobo evulekile. Kukhona futhi 'ukugoba' noma 'ukudlala' phakathi kwesiqu nebhola okuvimbela ukulawula okunembile. Okokugcina, inani le-torque edingekayo ukulungisa amavalvu ebhola alivumeli ukulungiswa okuncane eduze kwendawo "evaliwe" kanye "nevulekile".
