Pressure relief valves are safety devices designed to protect against excessive pressure buildup. They automatically release pressure from the heating system when it exceeds a predetermined set point, preventing potential damage to boilers, pipes, and other components.

Spring-Loaded Pressure Relief Valves: Utilize a spring mechanism to release excess pressure from heating systems before a dangerous buildup occurs.

Temperature and Pressure Relief Valves (TPR) are designed to relieve both excessive pressure and dangerously high temperature to protect heating system components and personal safety.
