Watts 0364195 Valve

The Watts 0364195, also identified by model 415-1 1/4-15, is a high-capacity steam pressure relief valve engineered specifically for low-pressure steam heating boilers. This ASME Section IV rated valve features a 1-1/4 inch NPT threaded inlet and a 1-1/2 inch NPT outlet, providing a substantial discharge path for overpressure protection. Set at a precise 15 PSI pressure relief, this unit is rated for a steam capacity of 1,265 lbs/hr, ensuring it can handle the BTU output of heavy-duty commercial and industrial boiler systems. The Watts Series 415 utilizes a bronze body and a silicone rubber disc-to-metal seal to ensure tight shut-off and positive reseating after a pressure event. For technicians replacing older units, this valve is a direct match for the Watts 415-1 1/4, maintaining the exact physical dimensions and seat specifications required for standard steam header configurations.

• ASME Section IV Certified: Meets rigorous safety standards for low pressure steam boilers.
• High BTU Capacity: Designed to discharge up to 1,265 lbs/hr of steam to prevent vessel failure.
• Durable Bronze Construction: Resists corrosion in harsh steam environments for long-term field reliability.
• Standardized Fit: The 1-1/4" x 1-1/2" footprint integrates seamlessly into existing industrial steam piping.
• Heat-Resistant Sealing: Features a silicone rubber disc for reliable operation at high saturated steam temperatures.

• What is the maximum pressure rating for the Watts 0364195? This valve is factory-set at 15 PSI for low-pressure steam applications and is not adjustable.
• Is this valve compatible with the 415-1 1/4 series? Yes, the 0364195 is the standard part number for the Watts 415-1 1/4-15 relief valve.
• Can this be used for water pressure relief? No, this is specifically a steam relief valve; water applications require different ASME certifications and internal configurations.
