Watts LFF115 3 X Lead-Free Pressure Reducing Valve, Ductile Iron, Flanged

The Watts LFF115 3 X is a 3" lead-free globe-pattern pilot-operated pressure reducing control valve with Flanged connections. It features a ductile iron body. Rated to 300 psi. This model is certified lead-free for potable-water installations.

This 3 inch globe pattern class 150 flanged epoxy coated pressure reducing control valve, model 115, is designed to automatically reduce a fluctuating higher inlet pressure to a constant lower downstream pressure regardless of varying flow rates. The quick closing action of the valve limits possible damaging high inlet pressure from passing through the valve to downstream piping. This valve has a fixed orifice closing speed, 2 isolation valves and 1/2 inch lead free pressure reducing valve. SentryPlus Alert® technology provides intelligent pressure monitoring and notifications using integrated sensors, and integrates with the Sensor Control Monitor to deliver maintenance alerts through BAS via RS-485 Modbus or the Nexa® platform over Wi-Fi.

Common Questions

What is the maximum working pressure?

This unit is built as 150# Flanged and is rated to 300 psi. End connection sets the ceiling on this platform, and 150# and 300# bodies are not interchangeable — confirm the class matches your flange drilling before ordering.

Is this valve certified lead-free for potable water?

Yes. The "LF" prefix denotes Watts lead-free construction, compliant with the weighted-average 0.25% lead requirement of the Safe Drinking Water Act (NSF/ANSI 372) for potable-water service.
