Two-Way Flow Altitude Valve

Series LFM127-2, LFM1127-2 Two Way Flow Altitude Valve is designed to open, allowing flow into a reservoir or elevated storage tank (tank fill), and close drip tight when high water level is achieved. The valve also opens allowing return flow (tank discharge), when upstream pressure falls below reservoir head pressure. It controls water level by remotely sensing static tank head pressure through a field installed sensing line, and opens when the water level is below the adjustable setpoint and closes drip tight when the level is above the adjustable setpoint.


  • Body and cover are constructed of strong and durable ductile iron (ASTM A536)
  • Allows fill and discharge in a reservoir or elevated storage tank
  • Simplified and efficient design is easy and economical to maintain
  • Water level is controlled by a field installed sensing line
