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.
Features
- Automatically limits flow rate to a constant adjustable maximum
- Flow control throttling action is controlled by an externally mounted Flow Control pilot
- Orifice Plate is factory calibrated based to meet requirements
- Body and cover are constructed of strong and durable ductile iron (ASTM A536)
