Features
- Designed to control the maximum water level in elevated water storage tanks
- The high level control is accomplished using a spring loaded 3-way altitude control and a large ported 3-way accelerator control
- The altitude pilot responds to the rising water level in the storage tank through a field installed sense line
- Altitude and Delayed Opening setpoints are separately adjustable
960GD-13-17 (Globe), 660GD-13-17 (Angle) Series is designed to control the maximum water level in elevated water storage tanks and to allow flow from the tank back into the water system after the system water pressure has fallen below the elevated storage tank shut-off head pressure by an adjustable amount of pressure. The high level control is accomplished using a spring loaded 3-way altitude control and a large ported 3-way accelerator control. The altitude pilot responds to the rising water level in the storage tank through a field installed sense line. The altitude pilot will signal the accelerator to open the main valve by venting the main cover chamber or close the main valve by pressurizing the main cover chamber. When the system pressure falls below the tank head pressure the Delayed Open for Return Flow feature is achieved by a normally open pressure control that holds the return flow line closed until the system pressure falls to the set point of the normally open pressure control.
