Watts LFF115-3 EC 6 Lead-Free Pressure Reducing Valve, Ductile Iron, Flanged

The Watts LFF115-3 EC 6 is a 6" lead-free globe-pattern pilot-operated pressure reducing & check control valve with Flanged 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 6 inch globe pattern class 150 flanged epoxy coated pressure reducing control valve, model 115-3, 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. Piloted with a check feature to close the valve when downstream pressure becomes greater than upstream pressure.

Features

• Globe pattern
• Class 150 flanged
• 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.
