CROSBY recommends to mount safety valve with spindle vertical for proper functionality.

However, you might give us more information on this question.
Why do you ask this question?
What is the inlet/outlet size of the safety valve?
Is there other valving involved?
What is the commodity in the line?
Other?

There is a Safety Relief valve mounted on one of the plunger pumps ( service wash water injection system). The safety relief is not functioning properly. I fully agree with you It is not good engg practiuce to mount a safety relief horizonatal
The inlet size is 1 1/2" and out let 2"
I don't understand why this particular safety relief is mounted horizontal??????

i.e. the setting includes the weight of the trim, spring etc...
for big valves this would create a significant difference between the shop setting and the field effective setting.
also... when installed horizontall they really look awful :oP

What about drainage or freezing?
Question the manufacturer's engineering staff, not the rep., about your application.
