I would like to ask about the installation direction of the circulating water butterfly valve
Thread Content
Now it is installed by following the arrow direction for the incoming water and against the arrow direction for the returning water, right?
As long as the water flow is in the same direction as the arrow, there’s no problem: lol
The water will flow in the direction consistent with the arrow on the check valve; there’s no mistake there.
The direction of the arrow indicates the main sealing direction
Just install it in the direction indicated by the arrow; there’s no need to deliberately remember the direction – don’t put yourself in a dead end
Normally, a valve is closed to seal the high-pressure side; when the return water flow is stopped, it is the high-pressure side behind the valve that is sealed, so the return water valve is installed in the reverse direction
A butterfly valve is a type of valve structure; there are butterfly-type check valves, as well as other types of valves that serve a shut-off function.
Check where the arrow is pointing – if it points in the direction of pressure, then the arrow is indicating the pump’s outlet; if it indicates the direction of water flow, then it should be installed in that direction. Pressure is usually indicated by the letter “P”, while the direction of flow is indicated by the letter “F”. You can ask the manufacturer what meaning the arrow represents~~
