FlowCheck—Gravity Check Valves
Honeywell FlowChecks prevent the flow of water to any part of a
system when the pump is shut off. They permit summer/winter
operation of indirect water heaters. Honeywell FlowChecks are
easy to clean. Just unscrew the top of the valve for inspection and
cleaning. Bronze and brass construction. To allow gravity flow, the
FlowCheck can be changed to manual operation by turning the
hand wheel counterclockwise (open position).
