Description
The Watts F121558 Relief Valve W/Flood Sensor Connectivity 7.77M BTU/hr 75 PSI 2″ Lead Free LF174A activates when internal pressure rises beyond its preset limit, releasing excess load through a calibrated discharge path to protect connected piping and equipment from over-pressurization in HVAC systems. Its integrated flood sensor connectivity enables external monitoring of abnormal discharge conditions, improving system visibility during operation. Designed for high-capacity hydronic and thermal processes, it responds instantly to pressure fluctuations to maintain controlled system stability while safeguarding downstream components from mechanical load.
