The Fisher™ V500 Eccentric Plug Valve is a heavy-duty control valve that combines the sturdiness of a globe valve with the efficiency of a rotary valve . It is engineered to deliver reliable performance in handling corrosive, coking, and other hard-to-handle fluids, providing precise control for both throttling and on/off operations .
Designed for severe service applications, the V500 features a robust construction with a streamlined flow passage and a wide selection of erosion-resistant trim materials, ensuring a long and reliable service life even in abrasive environments like oil sands and feed furnaces . Its eccentric plug design minimizes contact and friction with the seat ring during opening, reducing seat wear . The patented self-centering seat ring and sturdy plug provide tight shut-off for both forward and reverse flow directions .
Key Features & Benefits:
Tight Shut-off: The self-centering seat ring and robust plug ensure reliable Class IV shut-off (per FCI 70-2) for both flow directions .
Reduced Seat Wear: The eccentric plug path significantly reduces contact with the seat ring during opening, minimizing wear and friction .
Easy Installation & Alignment: The one-piece body flange fits a wide variety of pipeline flange types, simplifying alignment and installation while enhancing piping integrity .
Simplified Maintenance: Assembly is streamlined, as tightening the retainer requires no special positioning or separate alignment of the plug and seat ring .
Corrosion and Acid Resistance: Selected trim materials and body coatings help withstand highly corrosive applications, with trim and bolting materials suitable for acidic fluids and gases per NACE MR0175-2002 .
Durable Construction: Features sturdy metal or ceramic seat rings and plugs, an oversized one-piece valve shaft, and sealed bearings for reliable operation in harsh conditions .
