Pneumatic Steam Valve Help

larry_15 Member Posts: 55

There are a couple of things you need to know before ordering a pnuematic steam valve.

(1) The valve type: you can find this out by the brass tag around the valve it will hhave a number like vg2231-um845v5220 This will tell you what the cv rating is.

Next would be theactuators head A3000-1 Thsi will give them the spring range pressure.

You can call Johnson Controls tech support at 800-524-1330 go through the menu for material support and they can help you order the correct replacemant valve.

    Is this for replacement of existing valves? If so, are you utterly positive what you have cannot be re-built or re-conditioned?

    Johnson Controls used to make them when they were known as "Johnson Electric". Once saw them in an old mansion. I could not find anything similar at their website, but it's a bit difficult to navigate. You might want to call them.

    Otherwise I found angle valves in 1" and 1 1/2" but they were industrial controls and didn't look like they'd mount to a radiators. Found lots of 1 1/4" straight valves, but again industrial.

    Only things I saw in the way of pneumatics at Danfoss were again industrial. They're such a huge company it might be worth a call to their North American office.
