Regarding the installation sequence of the check valve and gate valve (stop valve) at the pump outlet, we hope everyone will share relevant links: http://bbs.hcbbs.com/viewthread.php?tid=771291&highlight=%B1%C3%B3%F6%BF%DA Installation sequence of pump outlet valves and check valves http://bbs.hcbbs.com/viewthread.php?tid=773395&highlight=%B1%C3%B3%F6%BF%DA Should a check valve or a stop valve be installed first at the pump outlet? http://bbs.hcbbs.com/viewthread.php?tid=773505&highlight=%B1%C3%B3%F6%BF%DA What is the difference between installing a check valve behind and in front of the pump outlet valve?

The stop valve should be installed first, with the check valve placed above it for easy maintenance.
Of course, a check valve should be installed first at the pump outlet, followed by a gate valve or globe valve.
1. The designs I’ve encountered all feature a check valve first, followed by a gate valve. 2. We felt that the gate valve should come first, followed by the check valve, so that’s how they were installed. 3. The design institute is not necessarily right; experience has taught us a lot.
In the pump houses we design, check valves are installed first, followed by gate valves. Check valves tend to develop problems easily. By closing the gate valve, the water in the pipeline will not flow back. Repair or replace the check valve
In our circulating water pump room, there is a check valve first, followed by a gate valve; there is also a gate valve in front of the pump to facilitate maintenance.
What do you mean? To save everyone time searching – it’s kind of interesting
Generally, a check valve is installed first at the pump’s outlet, followed by a shut-off valve; there’s actually nothing to argue about this
Install the check valve first, then the globe valve. Easy to maintain.
The check valve should be installed first, followed by the gate valve, to facilitate pipeline maintenance and valve inspection
Both situations exist at present. In our company’s process flow diagram, the valve that is shut off first is the stop valve, followed by the check valve
