Plug Valves

Plug Valve available in sizes ranging from 1/2″ – 72″ is designed specifically for wastewater applications. The round port design available on sizes 1/2″ – 12″, offers the least resistance to slurry, sludge, and fluid flow resulting in less erosion, longer service life, and reduced pumping costs. The large round port design can pass larger solids reducing plugging problems. Round port valves offer the best flow characteristics compared to alternative port openings, resulting in less pressure drop across the valve.

Manufactured in cast iron, using high pressure molding techniques for consistent quality and precision, the Eccentric Plug Valve also incorporates a nickel weld deposited seat for corrosion and erosion resistance, specially profiled for low torque and extended seat life. At DN65 epoxy seat only. The Eccentric Plug Valve is trunnion supported and fully encapsulated in an elastomeric polymer. The valve body is fully internally and externally Epoxy coated as standard. A rubber lined option is also available. Offering a high flow capacity with a round port design in sizes up to DN300 (larger sizes have rectangular ports), the Eccentric Plug Valve design ensures that the ductile iron plug rotates away from the seat as soon as movement begins, avoiding scuffing and thereby enhancing life expectancy.

Plug valves are valves with cylindrical or conically tapered “plugs” which can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug, so that fluid can flow through the plug when the valve is open.
