Watts 0384292 Valve

The Watts 0384292, also identified as the Series 740-2-50, is a heavy-duty boiler pressure relief valve designed specifically for large-scale hot water space heating applications. Engineered with a rugged iron body and a 2-inch FNPT inlet, this valve is factory-set at 50 PSI to protect hydronic systems from over-pressurization. It features expanded 2-1/2 inch NPT outlets to facilitate a high discharge capacity of up to 7,672,000 BTU/hr. This model utilizes a non-metallic disc-to-metal seating design, which prevents the disc from sticking or freezing to the seat even after long periods of inactivity. A stainless steel spring and a built-in test lever ensure reliable emergency safety relief. The Watts 740-050 is designed with the seat positioned above the drain to prevent sediment accumulation and water trapping, maintaining the integrity of the seal in demanding commercial and industrial environments.

• High BTU Discharge: Rated for 7,672,000 BTU/hr, making it suitable for high-output commercial boiler systems.
• Anti-Stick Seat: The non-metallic disc ensures consistent operation and prevents freezing against the bronze seat.
• Expanded Outlets: Features a 2-1/2 inch outlet to allow for unrestricted flow during emergency pressure relief events.
• Durable Construction: Built with an iron body and stainless steel spring to resist corrosive water conditions and mechanical wear.
• Optimized Drainage: Above-drain seat location prevents sediment buildup from fouling the valve mechanism.

What is the maximum operating temperature for the Watts 0384292?
This valve is rated for a maximum temperature of 250°F (121°C), suitable for most high-temperature hydronic heating systems.

Can this valve be used as an operating control for pressure regulation?
No, the Watts 740 Series is strictly an emergency safety relief valve and should never be used as a primary operating pressure control.

Is the 0384292 compatible with older Watts 740-2-50 units?
Yes, the 0384292 is the direct ordering code and is identical in fit, form, and function to the 740-2-50 50 PSI model.
