Watts 2.5-M1115FDA1A1B0H-0 2-1/2" Pressure Reducing Valve, Ductile Iron, Grooved

The Watts 2.5-M1115FDA1A1B0H-0 is a 2-1/2" angle-pattern pilot-operated pressure reducing control valve with Grooved connections. It features a ductile iron body. Rated to 165 psi.

This Watts 2 1/2 inch, angle pattern, grooved end, fire pressure reducing control valve 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 prevents possible damaging high inlet pressure from passing through the valve to downstream piping. This valve is UL listed for a 50-165 psi reduced pressure adjustment range. This valve includes epoxy coated ductile iron and corrosion resistant stainless steel stem and seat ring.

Features

• Angle pattern
• Outlet pressure adjustment range is 50 to 165 psi
• Grooved end construction for quick installation
• Corrosion resistant stainless steel stem and seat ring

Common Questions

What is the maximum working pressure?

This unit is built as GRV (Grooved) and is rated to 165 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 UL Listed and FM Approved for fire protection?

Yes — this model carries the UL listing and FM approval required for fire-protection service. Non-listed control valves cannot be substituted on a fire job even when the body and pilot are otherwise identical.
