Specifying Eccentric Plug Valves (PEC & PEF)

DeZURIK Eccentric Plug Valves (PEC & PEF)

Name: Eccentric Plug Valves
Brand: DeZURIK

Design Features:

DeZURIK Eccentric Plug Valves are used to handle clean and dirty liquids, sludge, slurries and gases. They can be used for either isolation/shutoff or throttling/control services.

The animation below shows how the Eccentric Plug Valve works. The quarter turn eccentric action and resilient plug facings ensure lasting bubble-tight shutoff. As the eccentric plug rotates from open to closed, it moves into a raised eccentric seat. When in the open position, the plug is out of the flow path. As the plug closes, it moves eccentrically toward the seat without scraping the seat or body walls, so there is no plug binding or wear! The resilient plug face makes full, uniform, firm contact with the seat for bubble-tight shutoff.

Eccentric Plug Valves feature a rectangular port design that provides wide tolerance seating geometry for lasting superior shutoff. The eccentric plug action and resilient plug facings assure lasting dead-tight shutoff. Standard features include corrosion-resistant bearings, welded nickel seat, grit excluders, and adjustable stem seal packing.

Port area options include 100% of standard pipe area for applications where highest flow is required (such as pumped systems), and 70/80% area for non-pumped (gravity feed) systems. The straight-through body design maximizes flow capacity and reduces head loss. Flanged or mechanical joint end connections are available.
