Watts 0382392 Valve

For high-capacity hot water space heating applications, the Watts 0382392 (Model 740-3/4-60) is the industry standard for reliable overpressure protection. Engineered with a rugged iron body and a 3/4" x 1" configuration, this ASME Section IV pressure relief valve is specifically designed to handle discharge capacities up to 1,566,000 BTU/hr. As an experienced contractor, you know the importance of keeping sediment away from the seat; this 740 Series valve features an above-drain seat design and non-mechanical disc-to-metal alignment to prevent sticking, freezing, or fouling from corrosive water conditions.

The Watts 740-3/4-60 is preset at 60 PSI and features expanded outlet drain connections to facilitate high-volume emergency relief. It incorporates a stainless steel spring and a high-temperature silicone disc to isolate working parts from the water supply, ensuring consistent performance up to 250°F. This model is identical to the 740-3/4-60 and serves as a direct technical replacement for high-demand hydronic boiler systems. Note that this is a safety relief device and must not be utilized as an operating control.

• High Discharge Capacity: Rated for systems up to 1,566,000 BTU/hr to ensure safety in large-scale residential and commercial heating setups.
• Anti-Foul Design: The seat is positioned above the drain to prevent water trapping and sediment buildup, reducing the risk of relief valve failure.
• Durable Construction: Features a heavy-duty iron body and stainless steel spring for longevity in harsh mechanical environments.
• System Compatibility: Standard 3/4" NPT female inlet and 1" NPT female outlet for seamless integration into existing boiler piping.

Is the Watts 0382392 suitable for potable water systems?
No, this valve is specifically designed for non-potable hot water space heating boiler applications and should not be used in domestic drinking water lines.

What is the maximum operating temperature for this valve?
The Watts Series 740 is rated for a maximum temperature of 250°F (121°C), making it ideal for high-temperature hydronic systems.

Can I install this valve horizontally?
For proper drainage and to ensure the test lever operates correctly, pressure relief valves should be installed in a vertical position according to ASME code and manufacturer specifications.
