Series SVS

Spraying unit of the series SVS

Spraying unit of the series SVS built into circular
sightglass to DIN 28120

Branch office / exclusive agent:

All dimensions in mm.

Application:
VETROLUX® spraying units of the series SVS may be used for cleaning the
inner face of sightglass discs via an intermittent, continuous or automatically
controlled spray. They are suitable in either safe or hazardous areas for
all standard sightglasses and may be used both for pressure and vacuum
vessels subject to test certification. According to your needs, we recommend
the mounting of several units into the same sightglass.
Mounting:
The mounting is made by means of a connection piece screwed into the
welding flange to form a pressure tight seal and through a clearance hole in
the cover flange.
Operating conditions:
These correspond to those of the sightglass used and it's rating.
Materials:
Contact parts:
Stainless steel
Gaskets:
PTFE
Possible combinations:
The spraying units may be used in conjunction with VETROLUX® wipers of the
series W / WD or WS together with the lightfittings of the series CHEMLUX®,
EdelLUX®, fibroLUX®, miniLUX® or metaLUX® without any restriction.
Connection:
The connection is made via a hole drilled into the welding flange, M14 x 1,5.
A clearance hole of ø 21 mm in the cover flange is also required.
Remarks:
- Dependent on operating conditions, a suitable non-return valve should be
built into the feed tube.
- When the spraying units are ordered complete with sightglasses, all the
necessary fitting requirements will be carried out at our works, as part of
the delivery.

materials for the welding and the cover flanges, 4) materials for the product
and cover side gaskets, 5) quality of the glass disc (borosilicate / sodium
