Watts F115-2 1 1/4 Lead-Free Pressure Reducing Valve, Ductile Iron, NPT

The Watts F115-2 1 1/4 is a 1-1/4" lead-free globe-pattern pilot-operated pressure reducing & sustaining control valve with NPT connections. It features a ductile iron body. Rated to 300 psi. This model is certified lead-free for potable-water installations.

This 1 1/4" Watts pressure reducing and sustaining control valve, model 115-2, 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.

Features

• Globe pattern
• NPT threaded
• Epoxy coated
• Copper tubing/brass fittings

Common Questions

What is the maximum working pressure?

This unit is built as THD (NPT Threaded) and is rated to 300 psi. Threaded and grooved bodies on this platform carry a higher working pressure than 150# flanged bodies, so do not assume a flanged datasheet applies here.

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.
