LFF114-3
Rate-of-Flow Control Valve with Hydraulic Check
Series LFF114-3, LFF1114-3 Rate of Flow Control Valve with Hydraulic Check Feature is designed to automatically limit flow rate to a constant, adjustable, maximum, and close drip-tight when downstream pressure becomes greater than upstream pressure. The throttling action of the valve is controlled by an externally mounted modulating control pilot, which senses differential pressure across a remote mounted orifice plate (field installed). The Orifice Plate is factory calibrated based upon minimum, maximum, and continuous flow rate requirements.
