Abstract
A vacuum breaker valve configured for clean in place capability is provided which includes a body having an internal passageway including a chamber, a valve member shiftable within the chamber, and a motive member positioned adjacent an upper end of the chamber for selectively displacing the valve member. The valve member closes the upper end of the chamber under backpressure to inhibit undesired discharge of the fluid in the chamber, while the motive member, such as a selectively shiftable plunger, serves to periodically displace the valve member away from the valve seat at the upper end of the chamber whereby fluid, such as a cleaning solution, may pass through the valve body and internally clean the vacuum breaker valve without the need for disassembly.
