Flush Bottom Y Type Globe Valve

Flush Bottom Y Type Globe 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.

BENEFITS

1.This type of valve is available in the size from 50 mm to 400 mm with different material of construction like Cast Steel, SS 304 ，SS 316 or any special alloy to suit user requirements. The valves seating are Teflon / Neoprene / Viton/STL depending on the process.

2.This type of valve is attached to the vessels on pad type nozzle. The disks in closed position match with the bottom of the vessel or piping leaving no room for hold up or stagnation.There are two types of flush bottom valves:Valves with disk opening into the tanks and Valves with disk into the valve.

3.In the first case the stem pushes the disk into the tank to drain the liquid. This type cannot be used when there are any internals which restrict the movement of the disk. The drain of the material could be effected completely. In the second case, the disk gets pulled down into the valve effecting the discharge of material.

4.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.

5.The parts of the flush bottom valve are identical to that of a globe valve and the closing and opening actions are also similar. The shut off is achieved by disk closing against the body seat.
