Description
The Bosch HVAC 87377034270 Safety Valve is a pressure relief element that protects plumbing systems by releasing excess pressure to prevent damage and unsafe operating conditions. It operates through a spring-loaded mechanism that opens when internal pressure exceeds a set limit, allowing controlled discharge until safe levels are restored. In HVAC systems, it is used in boilers and hydronic heating units to maintain pressure safety and system stability. It is connected within the pressure line of the system and supports equipment protection, safe operation, and consistent performance during high-pressure conditions.
