Fisher? 461 Increased Outlet Angle Sweep-Flo Valve
The Fisher 461 Sweep-Flo valve is a self-cleaning, increased outlet, angle valve that is typically used in the chemical and hydrocarbon industries where control of residual oils or other liquids with coking properties is necessary. The 461 features a venturi-type throat, which is useful in power plants or slurry services where high pressure drops and flashing might exist.
