Tlačno razbremenilni ventil SB
To prevent damage to the tank and help ensure safe operations, 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.
- Cost-effective, hygienic design
- Superior hygiene
- Customized to meet process requirements
- Easy to clean
The Alfa Laval SB Pressure Relief Valve is a dead weight safety valve. It is compliant with PED 97/23/EC, EN 4126-1 and EN 764-7 and is available in two versions:
- Integrated with a SCANDI BREW® tank top system
- Mounted on its own counter flange
The pressure relief valve is delivered with the counterweight set and locked at the preset pressure that meets the customer’s requirements for opening pressure. When pressure in the tank exceeds the preset opening value, the valve relieves the excess pressure.
The preset opening pressure must be set at a value that is above the tank working pressure: 0.1 bar above for working pressures <1 bar, and 10% above for working pressures ≥ 1 bar. The valve should be seated horizontally. A maximum inclination of 10° is acceptable, but the lever arm must then point inward toward the centre of the cylindroconical tank top.
The valve is cleaned in closed position by the tank cleaning head. However, this does not include cleaning of the valve seat. To include the valve seat as an integral part of the cleaning cycle, an optional pneumatic force opener and optional splash guard are available.
