S127-8
One-Way Flow Altitude Valve with Pressure Sustaining
Series S127-8, S1127-8 One Way Flow Altitude Valve with Pressure Sustaining Feature 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 throttles to sustain a minimum upstream pressure during tank filling operations. 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.
Features
- Allows flow into a reservoir or elevated storage tank
- Valve throttles to maintain a minimum upstream pressure during filling.
- Water level is controlled by remotely sensing static tank head pressure through a field installed sensing line.
