Vessels With Bottom Outlet Valve Seat

To fit a bottom outlet valve (BAL type) all spherical and cylindrical vessels can be supplied with valve seat in bottom outlet. For this, Add a suffix "/B" to the catalogue reference of a vessel, for e.g. 'VSL50' should be mentioned as 'VSL50/B'.

Notes on use of Spherical vessels :
  1. Generally, the centre nozzle, referred as DN in all types of vessels, is used for either stirrer fixing or, if stirrer is not fixed, for vapour outlet.
  2. The bottom outlet, referred as DN1 in all types, is used for drain. However, in type VSR & VSE, it is also used for fixing immersion heat exchanger.
  3. The small side nozzles, referred as DN2 in all types, are used (a) to fix thermometer pocket or
    1. to fix thermometer pocket or,
    2. to fix dip pipe for liquid inlet or,
    3. to fix sparger for gas purging or,
    4. to fix vacuum control or vent valve or,
    5. for solid addition.
  4. The bigger side nozzle, referred as Dn3, is used for vapour outlet where stirrer is fixed on centre neck. It can also be used for cleaning in case centre neck is used for vapour outlet.
  5. Vessels having long bottom outlet, viz VSM, VSPL, VSL, VS etc, can be supported in a heating mantle of heating bath. However, vessels having short bottom outlet, viz VSD, VSCY, VR, VA etc. are to be supported on a vessel holder only. In case of vessels upto 20L size, vessel holding rings can be used instead of vessel holder. *marked items are available fast.
