Distinguish The Application Of Ball Valve And Butterfly Valve

According to the selection of flow capacity, the flow capacity of the ball valve is better than that of the butterfly valve, because when the butterfly valve is in the open state, a butterfly plate in the valve body channel occupies a part of the flow channel. The smaller the diameter, the larger the proportion of the flow channel they occupy.

According to the use temperature selection, due to the sealing material and structure, the ball valve is not suitable for steam medium, while the butterfly valve can be used for conventional (below 350 ℃) saturated steam medium for heating.

According to the selection of the stress of the pipe network, due to the valve structure, the stress that the butterfly valve can withstand is higher.

According to the service life, the ball valve and the butterfly valve have a long service life, but the non-metal in the sealing structure of the ball valve plays an important role, and the metal-to-metal seal of the hard-sealed butterfly valve will have a longer service life.
