To minimise risk of damage to tanks due to overpressurising
or liquid overfilling.
The dead weight pressure relief valve is available in two versions:
Integrated in to a SCANDI BREW® tank top system
Mounted on its own counterflange
The advantages of an integrated pressure relief valve are
lower initial costs, superior hygiene and smaller area required
to seat valve.
The valve is available in the following sizes:
Diameter Operation Range
75 mm 1.0 - 3.0 bar (15 - 40 psi)
100 mm 0.5 - 2.0 bar (7 - 30 psi)
125 mm 0.5 - 1.5 bar (7 - 22 psi)
150 mm 0.5 - 1.0 bar (7 - 15 psi)
The size and setting of the pressure relief valve is based on
the tank design data and process requirements.
The preset opening pressure of the valve is normally at least
10% above maximum tank working pressure.
The pressure relief valve is produced in a sanitary and robust
All metallic parts: Stainless steel AISI 304
(or acc. to customer specification)
O-ring seal: NBR
All other parts: Non-toxic foodgrade materials.
Generally, to offer full protection against overpressurising and
liquid overfill, the active diameter of the pressure relief valve
should correspond to the tank inlet size. Heating elements
are available for valves exposed to sub-zero temperatures.
A heating tape is supplied for the flange mounted valves,
whereas valves integrated in a top plate are heated by means
of heating blocks mounted on the top plate close to the valve.
