Can anyone recommend a replacement for the neg pressure valve listed above

Tim McElwain

I did not get these from a

direct cross reference but I know they are negative pressure gas valves.

Robertshaw 7200DERN-680



Honeywell VK 8115



What is the valve your looking to replace used on? That would be of some help. Most of these negative pressure gas valves we see on equipment today do not have an after market replacement but you must go direct to the supply house who sells the equipment and then hope they also stock parts. Otherwise you have to go directly to the Original Equipment Manufacturer (OEM)

resolution (I hope)

tim , thanks again for your assistance. I inherited this job because the homeowner is a  friend. I was trying to help because the tech working on the boiler wasn't having much success. I'm told that he was actually in contact with the original designer of the boiler and even he couldn't help. My friend had no heat since thursday and was desperate so I took the hour ride to go have a look for myself. As I followed the flow charts it was time to check the gas pressure and lo and behold the burner fired when i flipped the switch back on ( didn't even want to disconnect the manometer) . I stayed for a few hours while the pipes thawed and burner cycled many times .Sometimes it's better to be lucky than smart, the other guy seemed to check all the right things.  I think we'll order the gas valve just to be safe.
