Regarding the arrow direction of butterfly valves
Thread Content
Does the arrow on the butterfly valve indicate the direction of fluid flow? Still in the compressive direction? The conclusions on Baidu are also different! I would like to ask the experts here.
The arrow on the butterfly valve should indicate the direction of fluid flow.
It is usually the flow direction of the medium; if it is in a pressure-bearing direction, it should be explicitly indicated in the instructions
The arrow on the butterfly valve usually indicates the direction of fluid flow.
If the direction is reversed, won’t it have much of an impact? In my setup, one pneumatic butterfly valve was installed in the wrong direction, but this didn’t cause any significant issues in actual operation
The arrow on the butterfly valve should indicate the direction of fluid flow.
The direction of medium flow is independent of the pressure applied
Under normal circumstances when installing a butterfly valve, there is no arrow on the valve body indicating the direction in which it should be installed; however, if an arrow is present, the valve should be installed in the direction indicated by that arrow. For triple-eccentric valves, the flow direction of the medium must be consistent with the direction indicated by the arrow on the valve.
:) The valves I have seen and used, those marked with arrows, indicate the direction of fluid flow. Butterfly valves, generally not labeled when symmetrical ； It is eccentric; it must be installed according to the arrow.
The direction of medium flow: wherever there is an arrow, it indicates the direction in which the medium flows. Butterfly valves, generally not labeled when symmetrical ； Eccentric; it must be installed according to the arrow
The arrow should indicate the direction of medium flow
