Two-Way Flow

Lead Free* Models Available

Description:

The WATTS ACV 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.
