Can a swing check valve be mounted vertically instead of horizontally?

Thanks in advance

Swing checks

Most (if not all) swing checks can be installed vertically.

Think I would qualify that statement that the flow must be up.

Maybe

But to be safe use spring checks on the vertical and swing checks on the horizontal. Dan

What John said...

if it is a swing check it can only be used in an up flow position for vertical. If you attemp to use it in a down flow position, gravity takes over and when it does see a back flow condition, it HAMMERS closed.

Thanks for the help. Flow will be up, I was concerned about resistance through a spring-loaded check valve. Is there a certain brand or type that has little resistance to flow?

Swing Checks

Look at the manufactures nomenclature.

The manufacturer calls these check valves horizontal swing check valves. That in its self is a tip.

It means swing checks should be used in a horizontal position.

It does not mean you can not use the swing check in a vertical position, but if you use the valve in a position it was not intended for you will suffer at least some CV slam.

In vertical positions use spring loaded check valves.

Incidentally, check valves are used mostly in conjunction with pumps. On any pump if a check valve is used you want to use a spring loaded check they operate a lot quieter than swing checks.

Spring checks

should work fine. Conbraco and others manufacture checks with "low pop" springs if you are really concerned. Find a brand with a soft seat to further eliminate noise at closing time

OR get a Grundfos Super Brute pumps with intergral spring checks. These are very flow friendly and soft seated.
