The Alfa Laval SB Tank Pressure Regulator maintains and regulates top pressure on pressure tanks during filling, processing and emptying. It usually connects directly to the gas/CIP pipe leading to the tank top or is incorporated into a flow panel. The regulator can be integrated with a Scandi Brew® tank top system.
The Alfa Laval SB Tank Pressure maintains the working pressure in the vapour space, or at the top, of a process tank during, filling, processing and emptying. It generally connects directly to the gas pipe or Cleaning-in-Place (CIP) pipe that leads in the tank top, or is incorporated into a flow panel. This ensures process safety and effectiveness as well as safeguards product integrity.
Alfa Laval SB Tank Pressure Regulator Application
The Alfa Laval SB Tank Pressure Regulator is a control valve that typically regulates the pressure in tanks used by the dairy, food, beverage, brewery and many other industries. The valve easily integrates with an Alfa Laval Scandi Brew® tank top system.
Standard design
The pressure regulator comprises a single valve unit including pressure exhaust valve, pressure supply valve and connection for pressure gauge. On top is a vent port with outlet connection. A tank connection at the side branch is normally connected to the pipe leading to the tank top. It is also possible to incorporate the pressure regulator in a flow panel.
Working principle
The valve unit has a variable setting, which enables adjustment of the relieving pressure to match the required working pressure in the tank. When tank top pressure exceeds the preset pressure, the regulator releases gas through the vent port – either for atmospheric discharge or for collection. If the tank top pressure decreases, a gas supply connection at the bottom of the valve allows gas to flow into the tank.
Benefits
- Reliable, constant tank pressure control
- Variable, pressure setting
- Optimized cleaning
- Built-in pressure gauge
- Fully cleanable with Cleaning-in-Place system.
Secure tank top pressure control
Maintaining the working pressure at the tank top is critical. The tank pressure regulator makes sure that the pressure in the vapour space of a process tank is always at the optimal setting. This ensure the safety and effectiveness of your processes and safeguards product integrity.
Modular hygienic design
All pressure regulator components are made of high-quality hygienic materials that meet stringent food and beverage processing standards. Modular design provides the flexibility to meet most installation requirements. Hygiene is assured through the use of a CIP adaptor to provide full cleanability.
Product benefits
- Constant tank top pressure during filing, processing and emptying
- Reliable setting of working pressure
- Fully cleanable with CIP system
Construction
The tank pressure regulator consists of single valve unit incorporating a pressure exhaust valve, a pressure-supply valve and a connection for a pressure gauge. The pressure-supply valve and a connection for a pressure gauge. The pressure regulator can be supplied with a valve with different versions of spring/regulating unit:
- Fixed setting (only one pressure)
- Variable setting
- Pneumatic actuator
Operating principle
The valve until is supplied either with a fixed setting or variable setting, which adjusts the relieving pressure to the required working pressure in the tank. When the tank top pressure exceeds the preset pressure, the regulator releases the gas through the vent ports either for atmospheric discharge or for collection. If the tank top pressure decreases, gas is supplied through the gas supply connection at the bottom.
Cleaning-in-place (CIP)
The tank pressure regulator requires cleaning between every batch. It is incorporated into the tank CIP procedure by means of the optional CIP adaptor. Before cleaning, the CIP adaptor is mounted onto the pressure regulator, it forces open the gas supply and pressure relief valve and enables them to be fully cleaned. During the CIP procedure, all functions are blocked.
Options
- CIP adaptor (T-piece and 180° band).
- Pressure gauge.
- Protection valve for pressure gauge when CIP pressure exceeds range for pressure gauge.
- Mounting brackets.
- Force opener.
- Mounting bracket on reverse side of valve block.
