Ductile Iron Pressure Reducing and Sustaining Control Valve with Downstream Surge Control Feature
The LF912GD-11 (Globe) and LF912AD-11 (Angle) Series is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, throttle to sustain a minimum upstream pressure, and quickly modulate toward closed when sudden high pressure downstream conditions occur.
- Automatically reduces a fluctuating higher upstream pressure to a constant lower downstream pressure
- Reducing, Sustaining, and Surge Control setpoints are separately adjustable
- Ideal for use when high capacity on-off equipment is installed downstream
- Closes quickly when downstream pressure exceeds surge setpoint
