Watts LFF115-2 150 4 Lead-Free Pressure Reducing Valve, Ductile Iron, Flanged

The Watts LFF115-2 150 4 is a 4" lead-free globe-pattern pilot-operated pressure reducing & sustaining 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 4 inch ACV is armed with ArmorTek®, a patented 3-part advanced epoxy coating system designed to limit both microbial induced (MIC) and exposed metal substrate corrosion. This pressure reducing and sustaining control valve is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, and sustain a minimum upstream pressure. This Classic valve style has a globe body pattern with class 150 flanged end connections.

Features

• Body construction with patented 3-part ArmorTek epoxy coating for advanced corrosion resistance
• Globe body pattern with class 150 flanged end connections
• Includes sustaining control valve
• Range 20-175 psi (standard)

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.
