Can a pressure relief valve be installed upside down?

It's best to mount pressure relief valves (PRVs) in a vertical position, which means it should be upright and the spindle should be vertical. While you can mount it facing upside down, this is not recommended.

RELATED QUESTIONS

Can a reduced pressure backflow preventer be installed vertically?
In a vertical arrangement, the reduced pressure principle backflow preventers don't work.
Can gate valves be installed upside down?
Gate valves can be mounted in different orientations around the pipe line, but the preferred orientation is the stem placed vertical. It is not recommended to install upside down. The performance of a valve is dependent on proper mounting. Is this true? The valve should be installed using the correct bolt size.
Can you adjust a pressure reducing valve?
There is an adjustment nut on the valve. To increase the pressure downstream from the valve, turn the nut clockwise. If you can't see the meter yourself, you should stop adjusting it when the pressure reaches the desired value.
Are pressure relief valves adjustable?
The user can adjust the relief pressure set-point by changing the force exerted by the reference spring.
Can a check valve cause low water pressure?
Check valve internals are more flow sensitive than on/off valves. Disc movement can occur inside the valve if there isn't enough flow. It results in wear, potential for failure, and a higher pressure drop than calculated.
Can a PRV be installed horizontally?
Installation that is horizontal is recommended. In a horizontal position, the valve can be installed. Is this true? Pressure relief protection on the downstream side of the reducing valve is needed to protect equipment.
