Scandi Brew (SB) Pressure Relief Valve
To prevent damage to the tank and help ensure safe operations, ABS offers the Alfa Laval SB Pressure Relief Valve protects a pressurized tank during an overpressure event. It is designed for hygienic processes in the brewery, dairy, food and beverage industries. The valve can be integrated with a SCANDI BREW® tank top system.

Effective pressure relief
This pressure relief valve removes excess liquid that creates overpressure in the tank due to overfilling. When pressure in the tank exceeds a preset value, the pressure relief valve opens to vent fluid in the event of liquid overfilling, and closes when the tank pressure has returned to a safe level.
Easy-to-clean hygienic design
Few moving parts and smooth, crevice-free stainless steel surfaces make this valve easy to clean. When the valve is in closed position, it is cleaned as part of the routine Cleaning-in-Place (CIP) cycle. For thorough cleaning of the valve seat, an optional pneumatic force opener and a splash guard is available.
Concept
The Pressure Relief Valve is used for minimizing the risk of damage
to tanks due to liquid overfilling.
Working Principle
The Pressure Relief Valve is delivered with counter weight set and
locked to suit customer requirements regarding opening pressure.
When pressure in the tank exceeds the preset opening value, the valve
relieves the excess pressure.
Standard Design
The Pressure Relief Valve is available in two versions:
• Integrated in a SCANDI BREW® tank top system
• Mounted on its own welding flange
Compliance to EN 4126-1
Compliance to EN 764-7
Compliance Pressure Equipment Directive 2014/68/EU of the
European Community, Fluida Group II
The advantages of an integrated Pressure Relief Valve are lower initial
costs, superior hygiene and smaller area required for the valve. The
size and setting of the Pressure Relief Valve is based on the tank
design data and process requirements.

Cleaning In Place (CIP)
The Pressure Relief Valve is cleaned in closed position by the tank cleaning head, but this will not include the valve seating. To include the valve seating
in the cleaning cycle, there is the option to equip the valve with a pneum. force opener and a splash guard.
