Sapag Series 1100 Safety Relief Valves

A soft sealed atmospheric safety valve with large flow capacity and soft seat tightness for steam condenser and turbine applications

Features:
• The Sapag Series 1100 steam safety valve
is used for the overpressure protection
of condensers normally operating under
vacuum.
• The valve has been specially designed to
limit the pressure that can incidentally
occur into the condenser at a level below
the value at which the condenser is to be
considered by local code or regulation as
a steam pressure vessel.
• This limit is 0.5 barg according to the
requirements of Pressure Equipment
Directive 97/23/EC for European
Community or 10 psig (0.69 barg)
according to the Heat Exchanger Institute
(HEI).
• Although the SAPAG Series 1100 soft
sealed atmospheric safety valve was
intended for steam condenser and
turbine applications, it can be used for
various applications on gas and vapors,
where its soft seat tightness performance
and large flow capacity match the service
requirements.
