Plug Valves
Function:
Plug Valve is the oldest known kind of valve. It is a commend assumption that the plug in the plug valve is taper (conic) . The fact is that there is a huge verity of the inside construction of a plug valve.
Operation:
The plug valve is a 90 deg (quarter turn) operated valve.
The main purpose of a plug valve is isolation, and it will than either be fully open or fully closed
The secondary function of the valve is regulation which is achived by tapering the valve bore. This will reduce the aperture of the plug.
Range of application:
• Oil production
• Water injection
• Mud systems.
• Shut down valve on production
• Water injection and test manifold
• Between valve tree and separator.
• Change-over valve between filters.
• Meetering stations
Options
Cylindrical
Cylindrical without seats (integrated sets in the valve body)
Full bore “through conduit”
Venturi with reduced bore
Maintenance:
As a rule plug valves are expected to be maintenance free, however for some valves maintenance is highly required to secure operation and avoid damage.
Plug valves are valves with cylindrical or conically tapered "plugs" which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, sothat fluid can flow through the plug when the valve is open. Plug valves are simple and often economical.

When the plug is conically tapered, the stem/handle is typically attached to the larger diameter end of the plug. Plug valves usually do not have bonnets but often have the end of the plug with the handle exposed or mostly exposed to the outside. In such cases, there is usually not much of a stem. The stem and handle often come in one piece, often a simple, approximately L-shaped handle attached to the end of the plug. The other end of the plug is often exposed to the outside of the valve too, but with a mechanism that retains the plug in the body.
