SB Anti Vacuum House
The Alfa Laval SB Anti Vacuum House is a vacuum safety valve housing that minimizes the risk of implosion in closed process tanks or vessels that are subject to vacuum conditions while emptying the tank, cool rinsing after hot-cleaning, or caustic cleaning in a CO2 atmosphere. It helps protect tanks from vacuum conditions that may cause tank implosion, damage or deformation. It can be combined with safety valves or pressure regulators mounted at the tank top.
Anti vacuum safety house minimizes the risk of implosion in closed process tanks
- Minimal risk of tank collapse due to internal vacuum conditions
- Fully cleanable via built-in Cleaning-in-Place nozzle
- Easy to integrate
- Low investment due to simplified installation
- Can be combined with other valves in a customized tank top
This is a cost-efficient, reliable and easy to install vacuum safety valve, it provides effective vacuum protection, while boosting process reliability, equipment and personnel safety. This anti-vacuum valve housing is designed for use in hygienic process tanks in the brewery, dairy, food, beverage and many other industries.
How does the vacuum safety house work?
Construction
Compliant with PED 97/23/EC, the Alfa Laval SB Anti Vacuum House consists of an AISI 316L stainless steel house, a vacuum tail and an EPDM seal. The valve can be used as an integral part of a SCANDI BREW® tank top system.
Operating principle
The anti vacuum safety house provides protection against tank collapse due to internal vacuum conditions. When used with safety valves, it helps protect the vessel and ensure discharge if pressure in the tank exceeds the preset opening value. When used with regulating valves, it helps ensure pressure relief if pressure in the tank exceeds the preset opening value.
Cleaning-in-Place (CIP)
During every tank cleaning cycle, a small volume of cleaning fluid (approximately 500 to 800 l/min.) will pass the valve body and clean the seat. To ensure thorough flushing of the valve seat, force opening of the valve is required and must be done when there is no pressure in the tank. The use of a drain collector is recommended to prevent the CIP fluid from spilling onto the tank.
Excellent valve cleanability
The vacuum safety relief valve makes it possible to achieve the exceptionally high levels of hygiene. Simply connect the unit to the main Cleaning-in-Place (CIP) system using a CIP nozzle. This enables fast and effective cleaning during the routine tank CIP cycle.
Effective vacuum protection
When high process safety and production reliability are critical, this vacuum safety relief valve help protect tanks from vacuum conditions that may cause tank damage or deformation and product leakage.
Cost-efficient, reliable and easy to install, it provides effective vacuum protection, while boosting process reliability and safety.
Versatile hygienic design
In addition to providing tank vacuum protection, the Alfa Laval vacuum breaker can be used in combination with safety valves or regulating valves to provide overpressure protection and process protection, respectively.
Options
For tank overpressure protection and process protection, the SB Anti Vacuum House can be combined with a CO2 house, pressure relief valve and pressure exhaust valve.
