Self-cleaning CO2 valves to control the flow of CO2 through tank top systems
The Alfa Laval SB Self-Cleaning CO2 Valve is a self-regulating valve that controls the flow of carbon dioxide through tank top systems and other. Designed for use in the brewery, food, dairy and beverage industries, this combined gas escape/supply valve makes it easy to vent or pressurize the vessel. The valve can be integrated with a SCANDI BREW® tank top system.
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.
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.
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.
