Maintain optimal safety and pressure regulation in your boiler system with the 181625 McDonnell & Miller relief valve. This essential component, designated as model 250-3/4-75, is designed to protect hydronic heating equipment by automatically discharging fluid if internal system pressure exceeds the factory set threshold.
This relief valve operates using a high-precision spring-loaded mechanism that ensures tight sealing during normal operation while providing rapid, reliable response during an over-pressurization event. Engineered for durability, the valve body and internal seat are constructed to resist corrosion and mineral buildup, ensuring consistent performance over the long lifecycle of your heating installation.
Key System Performance Baselines:
- Pressure Setting: Factory calibrated to open at 75 PSI.
- Connection Type: Standard 3/4" NPT inlet and outlet for easy installation.
- ASME Compliance: Rated to meet rigorous industry standards for boiler safety.
- Efficient Flow: Optimized discharge capacity to safely mitigate sudden pressure spikes.
⚠️ Application Profile: Primarily designed for use in hot water boilers, closed-loop hydronic heating systems, and domestic hot water supply tanks requiring code-compliant pressure relief.
