Watts 0342628 Valve
The Watts 0342628 (Model 315M2-015-Z4) is a high-capacity steam safety relief valve designed specifically for low-pressure steam heating boilers and industrial process equipment. Featuring a 3/4 inch NPT male inlet and a threaded female outlet, this valve is factory-set at 15 PSI for saturated steam service, meeting strict ASME Section IV requirements. The bronze body construction and stainless steel spring ensure durability in harsh environments, while the top-guided stem and non-stick PTFE-to-metal seating provide a positive shutoff and prevent galling. By positioning the seat above the drain, Watts has engineered this unit to eliminate water trapping and prevent sediment from fouling the internal components, making it a reliable choice for maintaining system integrity in commercial HVACR applications.
Key Benefits:- ASME Section IV Certified: Rated for safety significantly at a 15 PSI set point for steam heating systems.
- Enhanced Seat Protection: The seat is located above the drain to prevent sediment buildup and seat fouling.
- Superior Material Build: Features a rugged bronze body and a corrosion-resistant stainless steel spring for long-term reliability.
- High Discharge Capacity: Designed for high-flow steam relief to protect boiler jackets and piping.
- Non-Stick PTFE Disc: Ensures the valve opens reliably and seats tightly without sticking to the metal seat.
What is the discharge capacity of the Watts 315M2-015-Z4?
This valve is rated for a steam discharge capacity of 375 lbs/hr at the standard 15 PSI set point.
Can this safety valve be used for water pressure regulation?
No, the 315M2 series is specifically designed as a steam safety relief valve for emergency overpressure protection and should not be used as a primary water pressure reducing valve or operating control.
How often should the relief lever be tested?
In accordance with standard boiler maintenance, the valve lever should be operated manually at least once per year to ensure the waterways are clear and the internal disc moves freely.
