ʻO ka valve Butterfly i kapa ʻia ʻo flap valve, he ʻano maʻalahi o ka valve control, akā hiki ke hoʻohana ʻia no ka hoʻololi ʻana i ka pipeline medium switch control. ʻO ka valve Butterfly e pili ana i kahi ʻano valve nona ka ʻāpana pani (disc a disc) he diski, e hoʻohuli a puni ka ʻāpau valve e wehe a pani. Hoʻohana nui ia i ka ʻoki ʻana a me ka throttling ma ka pipeline. ʻO ka ʻāpana wehe a pani ʻana o ka valve butterfly he pā pelelele i hoʻopaʻa ʻia, e hoʻololi ana a puni kona axis i loko o ke kino valve, i mea e hoʻokō ai i ke kumu o ka wehe a pani ʻana a hoʻoponopono paha. Hoʻopili ʻia ka valve Butterfly i ka pipeline e lawe ana i nā media corrosive a me ka non corrosive fluid i loko o ka generator, gas, natural gas, liquefied petroleum gas, city gas, cold and heat air, chemical smelting and power generation and environmental protection engineering systems, i hoʻohana ʻia e. hoʻoponopono a ʻoki i ke kahe o ka waena.
