Is the check valve installed before or after the shut-off valve?
Are you referring to the pump outlet? ? ? Install a check valve first at the pump outlet, followed by a shut-off valve
Generally, before the shut-off valve, the fluid passes through a check valve to ensure the pipe is filled before air is expelled, and then the shut-off valve is used to control the flow rate.
According to the specifications, the valve should be cut off first, followed by the check valve
A check valve is installed first at the pump outlet, followed by a shut-off valve.
It should be installed before the stop valve, so that the check valve can function more effectively!
The check valve should be located near the side that can be accessed for maintenance
The check valve should be installed between the pump outlet and the isolation valve.
The specification seems to be a stop valve first, followed by a check valve
It should be installed at the pump outlet, between the pump outlet and the shut-off valve, to prevent the pump from rotating in reverse in case of power fluctuations, and to facilitate the maintenance of the check valve as well as the transfer of the pump. Under normal conditions, the check valve on the pipeline should be placed before the shut-off valve (in the direction of flow of the medium).
