LF910GD-15
Ductile Iron Pressure Reducing Control Valve with Solenoid (On-Off) Feature
The LF910GD-15 (Globe) and LF910AD (Angle) Series is a combination Pressure Reducing and Solenoid On-Off Control Valve designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, and open, allowing regulating action, or close drip-tight as commanded by the Solenoid Pilot. It is controlled by a normally open, pressure reducing pilot designed to: 1) Open (allowing fluid out of the main valve cover chamber) when downstream pressure is below the adjustable setpoint, and 2) Close (allowing fluid to fill the main valve cover chamber) when downstream pressure is above the adjustable setpoint. A decrease in downstream pressure causes the valve to modulate toward an open position, raising downstream pressure. An increase in downstream pressure causes the valve to modulate toward a closed position, lowering downstream pressure.
