Natural Gas Valve Identification

[Bill Yam]

Hi all, good day! I'm new to this and I'm desperately trying to identify a gas valve for a water tube boiler.
Does any one come across with this type/design of gas valve ?
Your help is greatly appreciated!

Well that's the strangest looking valve I think I've ever seen.

So unless someone just instantly knows you're going to need to give us more such as

Pictures
Location
Origin of the items
Any marks at all or logos
Size, pressure
Is the yellow thing the valve or the actuator?

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Indeed it is!
I got 1 photo only and it seem like no logos or marking on the yellow actuator.
Size wise estimated at 4" or 6", pressure inlet is 1 bar.

OK, Looks like it's a Kinetrol Pnumatic / gas powered rotary vane actuator.

I'm taking a guess here, but the power source might be the low pressure gas itself or an air supply of some sort.

These operate quarter turn ball valves or maybe butterfly valves. I assume there's a lot of lagging for some reason on those pipes and hence we can't see the valve underneath.

Oh that's so awesome!!!
Thanks LittleInch for the eagle eyes!
This both gas valve is positioned right before a modulating butterfly to gas inlet of Saacke system using DDCC.
I believe its function by pneumatic to open, somehow the site decided to insulate the valve body and makes it more difficult to identify.
