Eccentric Plug Valve 

Valvesonly is the leading Eccentric Plug Valve Manufacturer in USA. An electric plug valve is a style of rotary control valve with a plug-shaped, flow restricting member that follows an eccentric path as it rotates. The valves are outlined in such a way that it is only half of the cone or ball used to close the fluid flow. When it is in the fully open position, its plug is made to be out of the fluid flow and dented into the body. It helps to force the plug to oppose the seating surface for tight shut-off.

The eccentric plug valve works by rotating the plug for a 90o turn. To open the valve, the handwheel is rotated 90 degrees in the anticlockwise direction. This makes the plug make a quarter turn rotation and thus leaves the fluid passage open which then allows fluid flow through the eccentric plug valve. The fluid keeps flowing through the valve as the plug is not forced to seat back in the seating position. To close the valve, the handwheel is rotated in the clockwise direction for a quarter turn.

An important feature of the plug valve is its ease to adapt to multiport construction and these ports are widely used. It gives benefits like simplified piping and installation, and the removal of costly pipe fitting. Most plug valves are used for directional flow control, even in a moderate vacuum, handling gas and liquid fuel, for safe handling of extreme temperature flow like boiler feed water.

Advantages of Electric Plug Valves:

  • It is simple in design
  • It can be used in both high pressure and high temperature industries
  • These valves are free from fluid leakage
  • It has a few rotating components which help to reduce maintenance costs.
  • It operates quickly

Disadvantages of Electric Plug Valves:

  • Electric plug valves are heavy
  • The large-sized eccentric plug valves cannot be operated manually
  • It is not best for the throttling process.

Application of Eccentric plug valves:

  • Water Supply and Wastewater treatment
  • Steam power generating plants
  • Chemical Industries
  • Oil and gas Industries.
