Safe, reliable operation
The straightforward design of this gas management valve, featuring an internal polypropylene valve body and stainless steel spring, provides long-lasting operation. By minimizing the risk of overpressure or underpressure, the valve contributes to safe, reliable operation and maximum uptime.
Hygienic self-cleaning valve
Manufactured of AISI 316L stainless steel, the valve features a special drilled opening in the valve body, which effectively cleans all valve parts during Cleaning-in-Place (CIP). This minimizes the risk of contamination. Alfa Laval 3.1 traceability certification is also available upon request.
Construction
The valve consists of an AISI 316L stainless steel valve housing, spring, plug and EPDM seal. The valve housing consists of two components held together by a threaded connection. Inside there is a valve body made of polypropylene and a stainless steel spring to keep the body in open position.
The valve is typically positioned as an integrated part of the gas/CIP pipe at the top plate. It can be mounted at an angle of 45° (maximum) to the ideal vertical position. It can also be integrated with a SCANDI BREW® tank top system.
Operating principle
The stainless steel spring forces the valve body open, enabling the full flow of gas to pass through the valve in both directions. To force the valve body into closed position, CIP fluid flows in a countercurrent direction against the spring. Due to the force of the liquid, the valve closes. A special drilled opening in the valve body ensures hygienic cleaning of all valve parts.
Concept
Combined gas escape/supply valve to be used in tank top systems
and other applications for easy gas flow, allowing venting as well as
pressurizing of vessel through the valve. Partly-closed for CIP liquid
to be cleanable and self-draining.
Working Principle
The internal polypropylene valve body is force opened by a stainless
steel spring, thus allowing full gas capacity through the valve in both
directions. By introducing CIP flow against the spring force, the internal
valve body will be moved to a closed position.
The CIP liquid will close the valve but a special drilling of the valve
body ensures cleaning of all valve parts. Depending on valve size, this
CIP flow is approx. 800-900 l/h.
Standard Design
The valve housing consists of two parts held together by a threaded
connection. Inside there is a valve body and a spring to keep the body
in open position. The valve body is drilled to ensure internal cleaning of
the valve during CIP.
The valve is typically positioned as an integrated part of the
gas/CIP-pipe at the top plate. It can be mounted at an angle of
maximum 45° to the ideal vertical position.

Safe, effective pressure regulation
Easily integrated into a central process control system, this pneumatic valve ensures safe, reliable and hygienic performance by releasing pressure in the process tank when it exceeds the set point pressure. To ensure safe pressure regulations at all times, the set point pressure can easily be adjusted manually or from a remote location that is connected to the central control system.
Hygienic, easy-to-clean design
To meet exceptionally high levels of hygiene, this regulating valve features simple, straightforward design. Smooth surfaces and food-grade finishes contribute to superior hygiene and cleanability. For fast, effective cleaning, a cleaning nozzle is supplied for inline cleaning of the valve at the same time as Cleaning-in-Place of the vent/recovery mains takes place. Alternatively, an optional CIP supply valve is available to connect a CIP system directly to the valve housing.
Flexible valve mounting
With flexible mounting positions, the valve can be positioned directly on tank top, as part of a tank top system or elsewhere along the pipework as long as there is proper drainage from the valve housing.
Construction
The Alfa Laval SB Pressure Exhaust Valve consists of an AISI 316L stainless steel body, EPDM seals, and fittings for 4/6 mm nylon hoses for set point pressure and force opening. A cleaning nozzle and closing plug for the Cleaning-in-Place (CIP) inlet are also supplied. An optional pneumatic cleaning nozzle is available to replace the closing plug (see Options below). The valve can be used as an integral part of SCANDI BREW® tank top system.
Operating principle
The valve is operated by means of the set point pressure being applied to the top of a membrane set. The pressure regulation will be identical to the set point pressure. The set point pressure is either reduced to the required pressure by means of a manual precision regulator or an IP converter controlled by a PLC.
When the tank pressure exceeds the set point pressure, the valve will open and release pressure through the valve side branch for atmospheric discharge or collection. To ensure correct working conditions, there should be no backpressure after the vent port.
After force-opening of valve by means of an air signal to the lower part of the membrane set, the valve can be effectively cleaned either by using the cleaning nozzle for inline cleaning of the valve at the same time as CIP of the vent/recovery mains takes place, or by using an optional CIP supply valve to connect a Cleaning-in-Place system to the valve housing.
