SF150-CS-FFG-L-050 Flo-Tite 2 Carbon Steel Flanged Ball Valves, Uni-Flo SF150

The Flo-Tite Flanged Series are designed as a split body, two-piece construction, to allow ease of access for maintenance of the valve ball and seat without special tools. This line of valves utilizes the "free floating" ball principle. The ball is not fixed but is free to move with the line pressure. As a result, these valves are capable of tight shut-off with the flow in either direction or dead-ended, regardless of the position of the valve in the line. The downstream seat, which is opposite the pressurized side, of a closed valve, must carry the load exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase useful seat life by turning the valve end-for-end in the pipeline.Features:Full-Flo SeriesModels F150 Class 150/FG300 Class 300Full Port: 1/2" - 12"Standard Steam Working Pressure: 150 SWP, optional 300 psigUni-Flo SeriesModels SF150 Class 150/SF300 Class 300Reduced Port: 1" - 12"Standard Steam Working Pressure: 150 SWP, optional 300 psigDesign Features:Floating Ball DesignProtected Seat DesignO-Ring Backed SeatFire Safe Designed to API 607-5Spiral Wound Body Gasket with Secondary Metal to Metal SealOpen and Close Locking Device for Position Safety LockoutO-Ring Reinforced Stem PackingCryogenic Design • OptionI-SO-Mount, Actuator Mounting Pad StandardSuper-Tek SeatingLive Loaded Stem DesignAnti-Static Grounding DeviceSecondary Containment OptionFlatted Shaft - Positive Flow IndicationBall Cavity ReliefV-Ball Control • OptionMetal Seats Option, Class V & VI
