China Jacketed Plug Valve Manufacturer Shinjo Supplies Steam Jacketed Plug Valve, Class 150, 300, 600LB.

Plug valves are valves with round or conically tapered "plugs" which may be rotated within the valve body to manage flow with the valve. The plugs in plug valves have a number of hollow passageways going sideways with the plug, to ensure that fluid can flow with the plug once the valve is open. Plug valves are pretty straight forward and frequently economical.
