What is the application of this type of valve in manufacturing processes?
The upper and lower ball valves are used for purging the valve passage with a medium; therefore, this valve is intended for use in pipelines carrying solid powders or viscous, crystallizable materials.
The internal structure is not visible; it is guessed to be something like a check valve with a reverse flow plate! Then the two ball valves serve a purging function!
The valve appears to be a ball valve on tracks
For the flat gate valve, those two ball valves are connected to separate pipelines; since this type of valve has a DBB function, when it is closed, air and waste substances are discharged through those two ball valves connected to the separate pipelines
An electric valve with a purging port – it’s probably used for gas-solid or liquid-solid transportation!
First, I would like to know the grade and type of this valve. At present, it’s not clear whether it is a ball valve or a gate valve, nor whether it is a jacketed valve or some kind of large DBB combination valve. I hope experts can provide some clarification.
It’s a bit like jacket insulation, with two small pipes carrying the insulation water (steam)
