LFF115-43
Pressure Reducing and Sustaining Control Valve with Downstream Surge Control
Series LFF115-43, LFF1115-43 pressure reducing and sustaining control valve with downstream surge control feature is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, sustain a minimum upstream pressure, and quickly modulate toward a closed position when a sudden high pressure downstream condition occurs. The quick closing action of the valve prevents possible damaging high inlet pressure from passing through the valve to downstream piping.
Features
- Reduces a fluctuating higher upstream pressure to a constant lower downstream pressure
- Quickly closes when a high pressure downstream condition occurs
- Body and cover are constructed of strong and durable ductile iron (ASTM A536)
- Simplified and efficient design is easy and economical to maintain
