8.2.4. installation of the floor drain valve Type 2033
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 floor drain valve does not collide with other equipment components 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 Figure 14:.
→
Prior to welding the valve, grind the outlet wall.

Prior to commencing the welding process, check the charge number indicated on the supplied manufac-
turer's certificate 3.1.B.
procedure:
→
Position the flange into the hole so that the flange surface is tangent to the drain surface.
→
Tack 4 welding points and check the position of the valve.
→
Weld the valve evenly to the inside and outside of the container, with gas being supplied and using welding
material compatible with the valve's stainless steel 316L (DIN 1.4435).
→
Allow the welds to cool down before burnishing and cleaning them according to the applicable specifications.
These instructions assist in the installation of the floor drain valves and allow the prevention of deformation and
softening within the containers.
Please observe the applicable laws and regulations of the respective country with regard to the qualification
of welders and the execution of welding work.
