Conbraco 29-302L-45 Valve
The Conbraco 29-302L-45 is a high-performance ASME Section VIII pressure relief valve designed specifically for saturated steam applications. Built with a rugged bronze body and corrosion-resistant brass trim, this 3/4" MNPT x 1" FNPT valve is factory-calibrated to a 45 PSI set pressure. It features a National Board certified capacity of 231 lbs/hr, making it ideal for protecting small-to-medium steam boilers, sterilizers, and pressure vessels. The PFA Teflon soft seat design ensures superior seat tightness and resistance to boiler chemicals, significantly reducing simmer and leakage near set point limits.
Engineered for the demanding HVACR contractor, the Apollo 29 series valve utilizes a top-guided design and stainless steel springs to maintain consistent blowdown and reliable overpressure protection. The tapped body drain allows for efficient condensate removal, protecting the internal brass trim from mineral buildup. With a maximum temperature rating of 406°F, this steam safety valve meets rigorous CRN and ASME Code requirements for industrial and commercial pressure piping systems.
Key Benefits- Enhanced Sealing: High-grade PTFE soft seat provides bubble-tight shutoff and resists chemical degradation.
- Code Compliance: ASME Section VIII Div 1 certified and National Board capacity rated for legal system safety.
- Durable Construction: Features ASTM B584 bronze and rust-proofed steel components for long-term service in high-heat environments.
- Easy Maintenance: Simplified design with a lift lever for manual testing and integrated drain port for piping away discharge.
What is the difference between Section I and Section VIII ratings for this valve?
While some valves carry dual ratings, the 29-302L-45 is specifically Section VIII certified for unfired pressure vessels and steam service. A Section VIII valve cannot be substituted for a Section I power boiler application, though Section I steam valves are often permissible in Section VIII systems depending on local codes.
Can I install this valve horizontally?
No. To ensure optimal performance and prevent debris from interfering with the disc holder or seat, pressure relief valves must be installed in a vertical, upright position with the spindle perpendicular to the horizon.
Why is my steam valve simmering below the 45 PSI set point?
Most spring-operated safety valves may begin to "simmer" or warn at approximately 90-95% of the set pressure. For a 45 PSI valve, it is standard practice to maintain a system operating pressure at least 5-10 PSI below the nameplate setting to ensure a tight seal.
