Armature

Type 318V - PN2.5 (vacuum)

SHORT DESCRIPTION - ROUND TANK SIGHT GLASSES TYPE 318V (similar to DIN 28120)

 

Our tank sight glass fittings Type 318V are intended for welding installation into or onto a pressure vessel wall and provide a way to observe and illuminate the interior of the vessel. ACI tank sight glass fittings of Type 318V have been designed based on DIN 28120 for an operating pressure from -1 bar up to 2.5 bar. Two flanges of high quality stainless steel surround a glass disc made up chemically highly resistant borosilicate glass 3.3 according to DIN 7080, creating a nearly maintenance-free inspection port. For less demanding applications, soda-lime glass (DIN 8902) may be used.

Contrary to the sight glass fittings described in DIN 28120, our Type 318V is significantly thinner and the hexagon head screws barely protrude out of the cover flange, thus reducing the space required for installation. Type 318V (based on Type 318) is dedicated to low pressure and vacuum application.  

An O-Ring seal makes type 318V perfectly capable of vacuum applications.

Like the rest of our tank sight glass fittings, Type 318 BIO is available equipped with wipers or light fixtures. Read on to learn more technical details of our Type 318V!
