Flush Bottom Valve is a special purpose valve, which is used in piping, reactors and vessels to drain out abrasive, Slurry, Viscous Material or Semi Solid Media. This type of valve is available in the size from 15 MM to 150 MM with different material of construction like Cast Iron, Cast Steel, SS 304 / 316 or any special alloy.
This type of valve is available in the size from 15 MM to 150 MM with different material of construction like Cast Iron, Cast Steel, SS 304 / 316 or any special alloy to suit user requirements. The valves seating are Teflon / Neoprene / Viton depending on the process.
Normally, the inlet size of a standard flush bottom valve is one size higher than that of the outlet size . There are special constructions possible with both sizes same. The outlet port is at an angle to the inlet port . Normally 45 or 60 degrees deviation is provided. The end connections are normally flanged. However, smaller size sample/drain valves have been developed with welding end at inlet to withstand higher pressures. The maximum rating available at present for flanged valve is ANSI 300 lbs.
