The pneumatic butterfly valve on site is not eccentric, and there are no flow direction markings on the valve body. Does this mean that it’s not necessary to install flow direction indicators?

There are no flow direction requirements; horizontal installation is quite common at our level

There is no need to consider the flow direction; the sealing performance on both sides is the same

Ordinary centerline butterfly valves do not require orientation; they can be installed either horizontally or vertically

We don’t need to take this into account when installing here
