VIKING Fireking Eccentric Reducer – Grooved (VK-ER)

The VIKING Fireking VK-ER Eccentric Reducer is engineered to provide a size transition while maintaining a flat bottom or top alignment, preventing air pockets or drainage issues. Its ductile iron construction and grooved ends ensure durability, pressure integrity, and fast installation in fire-suppression systems.

Nominal Sizes: Multiple size combinations (refer to product datasheet)
Working Pressure: Up to 34.5 bar (500 psi), size dependent
Material: Ductile Cast Iron, ASTM A536 Grade 65-45-12
Connection Type: Grooved × Grooved
Finish: Painted (Red), Epoxy Coated, Galvanized

Prevents air entrapment in horizontal piping
Ensures proper drainage in fire-protection networks
Improves system reliability and hydraulic performance
Eliminates need for field-fabricated eccentric reducers
Suitable for high-pressure fire mains

Horizontal fire sprinkler piping, pump suction and discharge lines, and areas where maintaining a flat pipe profile is critical.

- DN32 × DN25 up to DN300 × DN250
Working Pressure: 16 bar (232 psi) up to 34.5 bar (500 psi), depending on size and approval
Material: Ductile Cast Iron, ASTM A536 Grade 65-45-12
Connection Type: Grooved × Grooved
Finish: Painted (Red), Epoxy Coated (on request), Galvanized

Maintains pipe centerline alignment, reducing system stress
Smooth internal profile minimizes pressure loss and turbulence
Eliminates welded or fabricated reducers
Faster installation with grooved mechanical joints
High pressure capability suitable for main fire lines

Fire sprinkler mains, risers, and distribution piping where a concentric reduction is required without offset, particularly in vertical installations.
