Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
Safeguard your commercial water heating system against dangerous over-pressurization and extreme temperatures with this reliable relief valve. The 100208443 by Lochinvar is designed to automatically discharge water if internal tank conditions exceed safe limits, preventing catastrophic tank failure. This thermal and pressure (T&P) safety device is a standard replacement part that integrates seamlessly into existing hydronic plumbing layouts.
This valve functions through an internal spring-loaded mechanism and a thermostatic element. When the water temperature nears 210°F or the pressure reaches the 150 PSI limit, the seal opens to evacuate excess heat and fluid, resetting automatically once the system returns to a safe operating state.
Key System Performance Baselines:
- Pressure Rating: Factory calibrated to 150 PSI for high-demand residential and commercial units.
- Thermal Capacity: Engineered to handle discharge ratings up to 95,000 BTU.
- Connection Compatibility: Features a 3/4-inch inlet and 1-inch outlet configuration for proper installation.
⚠️ Application Profile: Designed for primary use in water heater tanks, indirect-fired water heaters, and hydronic storage vessels requiring ASME-rated safety protection.
