107019 Bell \& Gossett SA 1-¼” Straight Angle Flow Control Valve

107019 Bell \& Gossett SA 1-¼” Straight Angle Flow Control Valve. The Bell \& Gossett straight angle flow control valve 107019 accomplishes two things. First the Flo-Control valve acts as a check valve, keeping the system flow from short-circuiting into places where it doesn’t belong. Second, and just as important, the Bell and Gossett Flo-Control valve stops hot water from migrating into a zone that’s not calling for heat.
