Watts 0298568 Regulator

The Watts 0298568 (Series LF223) is a heavy-duty, 1.5-inch high-capacity water pressure reducing valve designed for demanding commercial, industrial, and institutional plumbing systems. Engineered to handle high flow requirements while maintaining precise downstream control, this lead-free water pressure regulator protects sensitive fixtures and downstream components from the mechanical stress of excessive supply spikes. Its 1-1/2" FNPT threaded connections and cast copper silicon alloy body ensure a rugged, corrosion-resistant installation that meets strict lead-free compliance standards including NSF/ANSI 61 and ASSE 1003. Professional technicians rely on the LF223 for its enlarged diaphragm and oversized seat orifice, which provide superior pressure stability across variable flow rates. With a maximum working pressure of 300 PSI and an adjustable reduced pressure range of 25–75 PSI, this regulator is the standard choice for building main lines where reliable performance is non-negotiable.

Key Benefits

• High-Capacity Performance: Features an oversized diaphragm and spring cage specifically designed for high-volume flow applications without significant pressure drop.
• Lead-Free Reliability: Constructed from lead-free brass (copper silicon alloy) to ensure safe potable water delivery and compliance with domestic plumbing codes.
• All-Weather Durability: Equipped with a sealed spring cage, making it suitable for pit installations or accessible outdoor environments where moisture and debris are concerns.
• In-Line Serviceability: Designed for easy maintenance; the disc holder is removable for replacement without taking the entire valve body off the line.
• Wide Temperature Range: Features a reinforced Buna-N diaphragm capable of handling water temperatures from 33°F to 160°F.

Common Questions

What is the standard factory pressure setting for the Watts 0298568?
This regulator comes factory-set at 50 PSI, though it is manually adjustable across a 25–75 PSI range to meet specific site requirements.

Does this model include a thermal expansion bypass?
The Series LF223 typically includes an integral thermal expansion bypass feature, which allows water to flow back into the main supply if downstream pressure exceeds supply pressure due to thermal expansion.

Is the Watts LF223 suitable for hot water applications?
Yes, the high-temperature-resisting diaphragm is rated for use in both hot and cold water systems up to 160°F, making it versatile for commercial boiler feeds and domestic hot water loops.
