LFF115-74
Pressure Reducing Control Valve with Low Flow By-Pass
Series LFF115‑74 and LFF1115‑74 pressure reducing control valves with low‑flow by‑pass are designed to automatically reduce a fluctuating high upstream pressure to a constant lower downstream pressure, regardless of varying flow rates. Flow demands below the normal operating range of the main valve are managed by a separate, valve‑mounted, direct‑acting low‑flow by‑pass pressure reducing valve.
SentryPlus Alert® technology adds intelligent pressure monitoring and notification, using integrated sensors to track pressure fluctuations at up to three points and assess valve performance in real time.
When paired with an ACV, the Sensor Control Monitor kit issues maintenance alerts (such as when differential pressure rises above a preset limit) and communicates either through BAS integration via RS‑485 Modbus or through the Nexa® platform over Wi‑Fi.
The valve’s internals are protected by ArmorTek®, a multilayer corrosion‑resistant coating engineered to extend service life in demanding environments.
