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.
