Conbraco Industries 10-322-P50 Relief Valve

The Conbraco Industries 10-322-P50 Relief Valve is a high-capacity ASME Section VIII safety valve engineered for reliable overpressure protection in steam pressure systems. This bronze safety relief valve features a 3/4" Male NPT inlet and a 3/4" Female NPT outlet, specifically set at 50 PSI to manage discharge capacities up to 625 lb./hr. in industrial and commercial environments. Built with a corrosion-resistant bronze body and finished in polished chrome, it facilitates durability in demanding thermal conditions with a maximum temperature service of 312°F. As an ASME certified pressure valve, it is designed for precision opening and consistent reseating, making it a standard choice for hot water heating boilers and hydronic heating systems that require low-pressure steam relief. The compact design ensures easy integration into existing piping manifolds where steam boiler safety is the primary concern.

Key Benefits for Technicians:

• ASME Section VIII Certification: Verified performance for steam service pressure vessels.
• High Discharge Capacity: Rated for 625 PPH to prevent rapid pressure spikes.
• Internal Durability: Corrosion-resistant bronze construction maintains seat integrity under high-heat cycles.
• Ease of Installation: Standard 3/4" NPT connections allow for direct replacement in most boiler configurations.
• Polished Chrome Finish: Provides additional surface protection and a professional appearance for exposed mechanical rooms.

Common Questions & Answers:

What is the difference between Section IV and Section VIII ratings for this valve?
While often utilized in heating applications, the 10-322-P50 is specifically manufactured and tested under ASME Section VIII, which governs pressure vessels. This ensures it meets the rigorous standards for unfired steam applications and specific industrial process requirements.

Can this relief valve be used for water service?
This specific Conbraco safety relief valve is designed and calibrated for ASME Section VIII steam service. For air or liquid applications, a valve with the appropriate trim and certification for those specific mediums should be selected to ensure accurate blowdown and capacity.

Is the 50 PSI set pressure adjustable?
No, this valve is factory-set and sealed at 50 PSI. Tampering with the factory seal to adjust the pressure will void the ASME certification and potentially create a safety hazard within the steam system.
