Atmospheric relief valve type 1100
Installation and maintenance instructions
1. Description
Sapag atmospheric relief valves type 1100 have been selected for installation because of their
performance features, reliability and ease of maintenance. They are designed to protect vessels
under vacuum during normal operation against excessive pressure.
The tightness is achieved using a rubber seal seating on a stainless steel seat.
A water ring is provided on the disc to prevent any leak from the atmosphere to the vessel when it
is under vacuum.
Whenever part names are used in this manual, piece number in parenthesis follows. The piece
numbers are an aid to identifying the parts in Figure 1 and the relevant part list.

4. Safety precautions
Proper handling, storage, installation, maintenance and operation are essential to the safe and
reliable operation of any pressure relief product. The relevant procedures recommended by Sapag
and described in this manual are effective methods of performing the required tasks. Some of them
require the use of tools specifically designed for an intended purpose. These special tools should be
used when, and as recommended.
This manual contains various safety instructions which should be carefully read in order to
minimize the risk of personal injury, or the possibility that improper procedures will be followed
which may damage the involved Sapag product, or render it unsafe. The precautionary statements
given in this manual are by no means exhaustive. Pentair Valves & Controls cannot be expected to
know, evaluate and advise customers of all conceivable ways in which tasks might be performed,
or of the possible hazardous consequences of each way.
