SB Self-Cleaning CO2 Valve
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.
How it works
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.
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.
