Gate Valve installation
(OP)
Hi everyone, Could somebody give me a tip regarding the gate valves on horizontal line with its handwheel at horizontal position. If this arrange will not be of any problem in the future? The applications are for steam and liquid hydrocarbons.

If so then let's look at this in a logical manner.
What if we had a Gate Valve in a vertical line? The Stem would be in the horizontal position would it not?
So if a valve stem in the horizontal position is alright for a vertical line why would a valve stem in the horizontal not be alright for a horizontal line?

That wouldn't be one of those 50/50 situations.

M-5 STOP VALVES BETWEEN PRESSURE RELIEVING DEVICE AND VESSEL
(a) A vessel, in which pressure can be generated because of service conditions, may have a full-area stop valve between it and its pressure relieving device for inspection and repair purposes only. When such a stop valve is provided, it shall be so arranged that it can be locked or sealed open, and it shall not be closed except by an authorized person who shall remain stationed there during that period of the vessel's operation within which the valve remains closed, and who shall again lock or seal the stop valve in the open position before leaving the station.
