Watts 0382328 Relief Valve
The Watts 0382328 (Model 740-3/4-50) is a high-capacity boiler pressure relief valve engineered specifically for hot water space heating applications. This 3/4 inch NPT valve features a rugged iron body construction and is factory set at 50 PSI to provide critical overpressure protection for commercial and residential boiler systems. With a substantial discharge capacity of 1,352,000 BTU/hr, the Watts 740-3/4-50 ensures rapid pressure venting to maintain the structural integrity of the heating loop. Designed with a non-metallic disc-to-metal seating and a stainless steel spring, it resists corrosive water conditions and prevents sticking or freezing during long periods of inactivity. The expanded 1-inch outlet facilitates maximum flow during emergency discharge. Professionals select the Watts 0382328 relief valve for its ASME Section IV compliance and its clever design, which positions the seat above the drain to prevent sediment buildup and seat fouling, ensuring reliable reseating after operation.
Key Benefits- High BTU Rating: Delivers a 1,352,000 BTU/hr capacity, making it suitable for high-output heating systems.
- Foul-Resistant Design: The seat is elevated above the drain line to ensure sediment never gets trapped, preventing common valve failures.
- Anti-Stick Technology: Utilizes non-mechanical seat-to-disc alignment to eliminate sticking or freezing in the closed position.
- Expanded Discharge: Features a 3/4" female NPT inlet and an expanded 1" female NPT outlet to handle large volume discharge.
- Durable Construction: Built with a heavy-duty iron body and high-temperature water seals to isolate internal working parts.
Is the Watts 0382328 compatible with potable water systems?
No, this relief valve is specifically designed for non-potable hot water space heating boilers. It should not be used in domestic water heaters or plumbing systems providing drinking water.
What is the maximum operating temperature for this valve?
This 740 series valve is rated for a maximum temperature of 250°F (121°C), allowing it to withstand high-temperature hydronic heating environments.
Can the pressure setting be adjusted in the field?
The Watts 0382328 is factory set at 50 PSI. For safety and compliance with ASME Section IV, the pressure setting is fixed and should not be modified by the installer.
