The sequence of installation between check valves and ball valves
Thread Content
Today, the workshop is being renovated, and we plan to install a ball valve on the pipeline. There is already a check valve in place. The question now is whether the new ball valve should be installed in front of the check valve or behind it
———( )———|\|——————》》》》》》》 Flow direction: The ball valve is installed upstream of the check valve. Hey HY, the question you raised requires a fairly broad answer; check valves have many uses, and the choice depends on the specific circumstances! ~
Considering the replacement of the check valve, it’s better to have the ball valve downstream
It is recommended to install the check valve behind the ball valve! ! Because the function of a check valve is to prevent the material from flowing back! !
Considering the replacement of the check valve, it’s still better to have the ball valve on the upstream side
The ball valve is installed after the check valve, mainly because check valves usually have a change in diameter, resulting in high resistance and a tendency to get clogged. When they become clogged, closing the ball valve allows for replacement.
