Watts 0342624 Safety Valve
The Watts 0342624, also identified as the Series 315-M1-5, is a high-capacity steam safety valve designed specifically for low-pressure steam heating boilers. Engineered with a 3/4 inch NPT threaded inlet and a 1 inch NPT outlet, this ASME Section IV certified valve is factory set at a 5 PSI relief pressure. The construction features a durable bronze body and a top-guided stem to prevent fouling, ensuring reliable overpressure protection in commercial and residential hydronic systems. With a high BTU/hr discharge capacity, the 315-M1 series provides critical safety by exhausting steam rapidly when system limits are exceeded. For technicians replacing older low pressure steam valves, this unit offers a direct drop-in solution for maintaining code compliance and boiler integrity. Ensure the relief valve capacity matches or exceeds the boiler's gross output to prevent catastrophic failure during an overpressure event.
Key Benefits
- Verified Performance: ASME Section IV rated and National Board certified for 5 PSI steam applications.
- Rugged Construction: Bronze body and stainless steel springs provide corrosion resistance in harsh boiler environments.
- High Discharge Capacity: Designed for high-volume steam pressure relief to handle large BTU outputs.
- Standard Fitment: 3/4" NPT inlet allows for seamless integration into existing steam manifolds.
Common Questions
Can this safety valve be used for water pressure relief?
No, the Watts 315-M1-5 is specifically rated for steam. For water relief applications, you must use an ASME Section IV liquid-rated valve to ensure proper discharge rates.
What is the difference between a safety valve and a relief valve?
This steam safety valve is a "pop-action" device that opens fully at the set pressure, whereas relief valves open proportionally to the pressure increase, making this specific to steam boiler safety.
Is the 5 PSI setting adjustable in the field?
No. To maintain ASME compliance, these valves are factory set and sealed. Any tampering with the setting voids the safety certifications and creates a site hazard.
