Spraying units
for circular sightglasses
to DIN 28120 or similar
Series SV

Application:
VETROLUX® spraying units of the series SV 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.
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:
Gaskets:

Spraying unit, type SV 4, built into circular
sightglass similar to DIN 28120, DN 125, PN 6.

Stainless steel
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.
Delivery contents:
The complete set consists of a connecting angle piece, a distance tube and the
spraying jet head (see drawing left).
Connection:
The connection is made via a hole drilled into the welding flange, G1/4". A clearance
hole of ø 25 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
