Nts'etsopele ea li-valve tse laolang ho tloha qalong ea lekholo la bo20 la lilemo e bile lilemo tse 80 tsa nalane ea ho laola valve ka potlako ho felisa ho futhumatsa ho tloaelehileng ho hloleha ho ntlafala lihlahisoa tsa li-valve tse laolang, li-valve le li-positioners tse ikemetseng, joalo-joalo, ts'ebetso ea nts'etsopele ea li-valve le taolo ea li-valve e tjena: 20 s: Sephahla sa pele sa ho laola khatello bakeng sa botsitso se ile sa tsoa. 30 s: Ho ea ho "V" mofuta oa "valve ea setulo se habeli" le valve ea setulo se le seng bakeng sa lihlahisoa tsa mofuta oa V-valve e laolang bolo e tsoile. 1940s: Ho hlaha ha boemo, mefuta e mecha ea li-valve tse laolang li hlahisoa hape, valve ea diaphragm, valve ea Angle, valve ea serurubele, valve ea bolo joalo-joalo. 1950s: Balofo ea bolo e 'nile ea sebelisoa haholo, valve ea litsela tse tharo ho e-na le li-valve tse peli tsa setulo se le seng tsamaisong. Lilemong tsa bo-1960: Kamora ntlafatso e hlophisitsoeng le maemo a lihlahisoa tse kaholimo Chaena, ho ile ha hlahisoa letoto le felletseng la lihlahisoa China. Hona joale re ntse re sebelisa palo e kholo ea li-valve tsa setulo se le seng, li-valve tsa litulo tse peli, valve ea Angle, valve ea litsela tse tharo, valve ea diaphragm, valve ea serurubele, lihlahisoa tse supileng e ntse e le boemo ba lihlahisoa lilemong tsa bo-1960. Ka nako ena, linaha tse ling li ile tsa qala ho hlahisa mofuta oa borobeli oa sebopeho se laolang valve - valve ea sleeve. 70's: Sebopeho se seng se secha sa sehlahisoa - eccentric rotary valve e ile ea tsoa. Nakong ena, li-valve tsa sleeve li ne li sebelisoa haholo linaheng tse ling. Ho elella bofelong ba lilemo tsa bo-1970, moralo o kopanetsoeng oa malapeng oa valve ea sleeve, e le hore Chaena e be le lihlahisoa tsa eona tsa lihlahisoa tsa li-sleeve valve. 1980s: Nakong ea ho bula, China e atlehile ho hlahisa sesebelisoa sa petrochemical le theknoloji ea li-valve tse laolang, e le hore valve ea sleeve, eccentric rotary valve e tumme le ho sebelisoa, haholo-holo valve ea sleeve, e na le monyetla oa ho nka sebaka sa setulo se le seng le se habeli, tšebeliso ea eona e ntse e ata le ho feta. Qetellong ea 80's, regulator ke tsoelo-pele e kholo ho Cv3000 ea Japane le molaoli o motle o monyenyane, ba ka sebopeho, mochine o le mong oa filimi ea pneumatic ea selemo ka har'a mochine oa lifilimi oa li-multi-spring, sebopeho sa valve se ntlafalitsoe feela, ha sea fetoha.
