Can you install a ball valve upside down?
Consequently, does it matter which way a ball valve is installed?
In short: a ball is round so direction does no matter. If a valve must be installed in a certain direction is should have an arrow cast into the body showing the direction of flow.
Secondly, can a gas valve be installed upside down? It has always been my understanding that a combination gas valve can be installed in any orientation (0-90 degrees) other than upside down.
Consequently, can a pressure relief valve be installed upside down?
We advise no; keep the body above the horizon when mounted in a horizontal pipe, or mount it in a vertical pipe.
Which direction is open on a ball valve?
When the handle of a ball valve is parallel to the valve or pipe, it's open. When it's perpendicular, it's closed.
