Ginbutterfly valveki yubu i lobo Amerika i mwaka 1930s. Ki kelo i Japan i mwaka 1950 ki onwongo pe ki tiyo kwede i Japan nio wa i mwaka 1960. Pe ki ngeyo i lobo na nio wa i mwaka 1970s. Gin ma pire tek i kom butterfly valves tye: teko manok me tic, kabedo manok me keto ki pek ne yot. Kwanyo DN1000 ma calo labol,butterfly valvetye ma romo 2T, ma nongogin ma ki lwongo ni gate valvetye ma romo 3.5T. Ginbutterfly valveyot me ribbe ki jami ma pat pat ma ki tiyo kwede ki tye ki teko maber ki genne. Peko pa jami ma ki lwongo ni rubber-sealed butterfly valves tye ni ka ki tiyo kwede me juku yamo, cavitation obi time pi tic kwede marac, ma weko kom ma ki yubu ki rubber ni twero rweny ki balo. Pi meno, kit me yero ne maber cung i kom kit ma en tye ka tic kwede. Wat ma tye i kin yabo pa butterfly valve ki rwom me mol pa pii tye ma rwate. Ka kitiyo kwede me doro rwom me mol pa pii, kit ma mol kwede bene rwate ki rwom me mol pa paip. Me labolle, ka rwom me valve ki kit ma tye kwede pa paip aryo ni rom, ento rwom me rweny pa paip ni pat, rwom me mol pa valve ni bene obi bedo pat pat. Ka valve ni tye i rwom me throttling amplitude madit, cavitation twero time i nge valve plate, ma twero balo valve ni. Pol kare ki tiiyo kwede i 15°. Kabutterfly valvetye i dyere ma oyabe, dul ma oyabe ma ki yubu ki kom valve ki agiki me anyim pa butterfly plate tye i kin valve shaft, ki kit ma pat pat ki yubu i tung aryo weny. Agiiki me anyim pa gin ma ki lwongo ni butterfly plate ni tung acel woto i yoo ma pii mol iye, ki tung cing mukene ni woto i tung ma pii tye ka mol iye. Pi meno, kom valve ki valve plate ma tye tung acel gi yubu doggola ma nen calo nozzle, ki tung mukene ni rom ki doggola ma nen calo throttle hole. Tung ma ki lwongo ni nozzle tye ki rwom me mol ma lamal loyo tung ma ki lwongo ni throttle, ki teko ma pe ber obi bedo i te valve ma tye tung throttle, ki gin ma ki lwongo ni rubber seal ni obi poto piny. teko me tic pabutterfly valveloko pi yabo ma pat pat ki yoo me yabo ki cego pa valve. Teko ma ki nongo ki i apoka poka ma tye i kin wi pii ma malo ki ma piny pa valve ma ki lwongo ni horizontal butterfly valve, tutwale valve ma dit, pi dit pa pii, pe kitwero cayo ne. Medo ikom meno, ka ki keto elbow i kom donyo pa valve, bias flow bedo tye, ki torque bi mede. Ka valve ni tye i dyere, gin ma tiiyo kwede omyera obed ma ocung kene pi tic pa pii ma mol.
China tye ki jami mapol ma ki yubu ki valve, ento en pe tye ki teko me valve. Ka i lok, lobo na odonyo i kin lobe ma tye ki teko me valve, ento i lok kom rwom me jami ma ki yubu, lobo na pud tye ka mabor ki bedo lobo ma tye ki teko me valve.
