Watts F1115-3 1 1/2 Lead-Free Pressure Reducing Valve, Ductile Iron, NPT

The Watts F1115-3 1 1/2 is a 1-1/2" lead-free angle-pattern pilot-operated pressure reducing & check control valve with NPT connections. It features a ductile iron body and a epdm seat. Rated to up to 300°F. This model is certified lead-free for potable-water installations.

This 1 1/2", angle pattern, Watts pressure reducing and check valve, model 115-3, is designed to automatically reduce a fluctuating higher upstream pressure to a constant lower downstream pressure regardless of varying flow rates, and close drip-tight when downstream pressure becomes greater than upstream pressure.

Features

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

Common Questions

What fluid temperature can the EPDM trim handle?

This valve is built with EPDM elastomers, good to about 300°F. Watts offers the same body with Buna-N (to 160°F), FKM/Viton (to 250°F) or EPDM (to 300°F) — pick the elastomer for your fluid temperature, not the body.

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.
