Can anyone tell me what is required for a shutdown valve on a fuel train for an indirect line heater to obtain FM approval? The reason I ask is we are bidding a job to a client that wants FM approved valves on the fuel train but they want the bare minimum for cost reasons. I have always used a...
One of the guys here is fluent in Spanish so we are going to conference call the company and try to get this figured out. I will post what I find out.

I have no idea what this abbreviation stands for:
LOR
It is on a motor starter panel with "START" and "STOP" pushbuttons. It is on the same type of symbol as the start and stop so I am assuming it is a pb also. Any help would be greatly appreciated. The drawing came from a company in...
I found a 2nd edition of Moss' book here at work and it had a "lite" cover of dust on it. Evidently one of the engineers who used to work here left it and it was marked up pretty good. I think I will stick with Megyesy's book and call it good for now. Thanks again for all the input.
I have Eugene F. Megyesy's "Pressure Vessel Handbook" and find it to be an invaluable resource. My question is does anyone have Dennis R. Moss' "Pressure Vessel Design Manual" and if so would you recommend it as a complement to the one I already own. I am just curious if...
This arcing and sparking will take place next to an open source of natural gas...the pilot assembly and burner nozzle on one end. This is in a flame arrestor assembly so there is no classification. On the other end the coil is in a purged NEMA 4 box and in a Class I Div II area and that meets...
Thanks for all the replies and ideas.
peebee,
The motor and dist in the panel are out of the question. This is something that a company like Shell or PMEX would be looking to purchase. The Class I Div II rating is at these company's request so that is the rating I have to deliver.

melone,
there is no distributor involved. that is what i am trying to eliminate. for simplicity sake this is a one cylinder engine that needs a continuous spark as long as the push button is pushed.
skills,
thank you. i will try this tomorrow.

the reason is this is going into the field on a natural gas heater. the enclosure will be air purged so it walks the Class I Div II rating. know that a dist and a DC motor will do the trick but it is not feasible in the field.

Skills,
You seem to be on the same page with me. I understand a battery will be needed. The system will work off of a 12VDC 7Ah battery. I just mocked the system up and got it to spark for everytime I depressed the push button. So for multiple sparks I had to manually cycle the pushbutton...
i have done some research on the web and now i understand what you guys are talking about and think i have a way figured out. i talked to the electrician here and we have devised a way to bench the system. thanks for all the information. could be a lot of fun but what the heck its Friday, no...
