The document summarizes DeZURIK eccentric plug valves. Matt DeZurik designed the first eccentric plug valve in 1928 to reduce pine pitch buildup in paper mills. Since then, DeZURIK valves have expanded to many industries. The eccentric plug valve design uses a half plug for high seating force and shut-off capabilities with minimal friction. DeZURIK eccentric plug valves are available in sizes up to 72 inches and can provide bubble-tight shutoff depending on size. They are used in various applications like wastewater treatment, pumps, and more.

1. ECCENTRIC PLUG VALVES

2. DeZURIK Inc
 When Matt DeZurik worked at the Sartell Paper Mill, the owner
asked the young, inventive man to design a valve that would
dramatically reduce pine pitch buildup during the
manufacturing process. He did it, and the DeZURIK Eccentric
Valve was born. It was introduced to the industry in 1928, and
despite the economics of the Depression, paper
manufacturers recognized its advantages and sent in their
orders. Since then, the DeZURIK name has expanded beyond
the pulp and paper industries. The brand is now standard
equipment in every industry requiring dependable valves,
consistency transmitters, actuators and accessories.
 Also, DeZURIK has been in the business of providing solution
to pump system regulation since 1932

3. ECCENTRIC PLUG VALVE
 The design of this plug valve uses a half plug that is
advantageous for applications needing a higher seating
force with minimal friction from open to closed position.
The torque seated valves also feature improved shut off
capabilities.

Working Method
 With the cylindrical plug and rectangular port of the
DeZURIK Eccentric plug valve, exact plug to seat
alignment is not required. Axial alignment is not an issue ,
as it does not affect seat contact. Rotational alignment is
provided by the eccentric action of the plug as it moves
into the seat making uniform, full contact. Without the
need for exact alignment, the plug shutoff position has
much wider tolerances and provides more reliable
shutoff.

10. DeZURIK Plug Valves Material Of
Constructions
 DeZURIK has a material combination to meet applications needs
 Aluminum body and plug combination is used where moderate
Hydrogen Sulfide and moisture are carried in the piping system
 Aluminum body and stainless steel plug combination is used
where corrosive moisture might enter the plug journals
 Soft rubber-lined body and stainless steel plug combination
provides protection against most other digester gas applications
 Cast iron body and stainless steel plug combination is used where
are moderately dry and economics dictate the use of cast iron
