DeZURIK IncECCENTRIC PLUG VALVES

DeZURIK IncWhen 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

ECCENTRIC PLUG VALVEThe 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.

DeZURIK 3”Eccentric Plug Valve 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.
