Eccentric butterfly valve, double eccentric butterfly valve, triple eccentric butterfly valve – is there a flow direction?
There should be a flow direction; an arrow is usually on the valve body.
There is a direction; it cannot be installed backwards. The steering direction of the actuator must be consistent with its flow direction; otherwise, problems will arise.
The direction of the arrow on the butterfly valve indicates the direction of the medium pressure acting on the valve when it is closed and sealed; it does not represent the flow direction
There is a direction of flow, but nowadays import valves can also be installed on both sides. For example, the Metso brand
If it’s installed backwards, it may not open under high pressure
The arrow on the valve body should indicate the flow direction, right?
The direction of the medium pressure and its flow direction should be the same, right?
In what situations is eccentricity mainly used?
