Armstrong Fluid Technology 216942-300 Valve
The Armstrong Fluid Technology 216942-300 Valve is a precision-engineered 1/2" NPT Brass Hot Water Pressure Relief Valve designed for high-performance hydronic heating systems. Factory-set at a 30 PSI relief pressure, this RL-11 relief valve serves as a critical safety component by automatically discharging excess pressure to protect boilers and downstream piping from structural damage. Constructed from high-grade, corrosion-resistant brass, it ensures reliable operation in demanding residential and commercial hot water boiler environments. The Armstrong 216942-300 features a robust stainless steel spring and a non-sticking seat design to prevent sediment buildup, maintaining system integrity over long-term use. Its compact 1/2 inch NPT connection allows for seamless integration into existing fluid-flow setups, making it an essential HVAC replacement part for technicians seeking to maintain peak safety standards in low-pressure water systems. This heavy-duty boiler safety valve is specifically calibrated for emergency pressure release, providing peace of mind and operational efficiency for your heating infrastructure.
Key Benefits- Precise Pressure Control: Pre-set at 30 PSI to prevent system over-pressurization and potential boiler failure.
- Durable Brass Construction: High-quality brass body provides superior resistance to corrosion and mechanical wear.
- Enhanced System Safety: Protects pipelines and equipment from sudden pressure surges or thermal expansion.
- Easy Installation: Standard 1/2" NPT threaded connections facilitate quick and secure fitting into hydronic loops.
- Maintenance-Free Reliability: Engineered with a stainless steel spring and specialized seating to resist sticking or freezing.
What is the maximum pressure rating for the Armstrong 216942-300?
This specific model is a fixed-pressure relief valve set at 30 PSI, ideal for standard hot water heating boiler applications.
Can this valve be used for potable water systems?
The 216942-300 is primarily designed for non-potable hydronic heating and closed-loop hot water systems. Always check local plumbing codes before installation.
Does this valve require regular testing?
Yes, HVAC professionals recommend periodically activating the test lever to ensure the waterway is clear and the internal spring is functioning correctly.
