8.2.5 installation of the tank bottom valve
Type 3235
For further information on containers and welding instructions,
please refer to the standard ASME VIII Division I.
It is recommended to weld the valve prior to the container
installation. However, it is possible to weld the valves to ready-
assembled containers.
prior to welding, please check to ensure that:
• The tank bottom valve does not collide with other equipment compo-
nents and assembly/disassembly of the actuator is always possible.
• A minimal distance between two welding joints three times the
thickness of the container wall is adhered to.
It is recommended to weld the valve in the center of the drain
to ensure optimum draining of the container.
The diameter of the hole in the container and the flange must be equal.
The valve has two welding edges to make welding and positioning
of the valve easier. The length of the welding edges is approximately
3 mm. In case the thickness of the container wall exceeds 3 mm, the
valve must be positioned as shown in Fig. 9.

Prior to welding the valve, grind the outlet wall.
