Pressure Reducing with Hydraulic Check Valve - Full Port
Series LFM115‑3 and LFM1115‑3 pressure reducing and check valves are designed to automatically reduce a fluctuating high upstream pressure to a constant lower downstream pressure, regardless of varying flow rates. The valve closes drip‑tight when downstream pressure exceeds upstream pressure, preventing reverse flow through the 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.
Features
