Watts 8-M115FCA1A1B0H-0 Pressure Reducing Valve, Ductile Iron, Flanged

The Watts 8-M115FCA1A1B0H-0 is a 8" globe-pattern pilot-operated pressure reducing control valve with Flanged connections. It features a ductile iron body. Rated to 300 psi.

This Watts 8 inch, globe pattern, class 300 flanged, 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

• Globe pattern
• Outlet pressure adjustment range is 50 to 165 psi
• High pressure Class 300 flanges
• Corrosion resistant stainless steel stem and seat ring

Common Questions

What is the maximum working pressure?

This unit is built as 300# 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 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.
