Vacuum Breakers
Model GHVB air-operated vacuum breakers are used to eliminate vacuum on the downstream side of the pasteurizer in an HTST system. It is truly CIP-able, needing only one air connection for CIP control. GHVB is authorized to carry the 3A symbol.
Models A49-42 and B44MP vacuum breakers are designed for line service only. They are not intended for use on tanks or vessels. Their typical application is at the high point of an HTST system to prevent siphon or back flow in the system.
Model A49-42 is offered with a 2" Tri-Clamp connection only. It uses a diaphragm that seals against a perforated plate. Under vacuum, the diaphragm pulls toward the product and allows air to enter the system. The diaphragm is standard on Buna material, all other wetted parts are 316.
Model B44MP is available in 1-1/2" and 2" Tri-Clamp connection. It uses a teflon plug and o-ring design. Positive pressure keeps the o-ring sealed against the base. During vacuum the plug and o-ring drop down allowing air into the system. The standard o-ring is Buna, but can be changed to other elastomers. Other wetted parts are 316.
Both units have a small bell hood on top to direct any product blow-by down towards the floor. |
