Description
The Watts F276890 Pressure Relief Valve is a safety unit that controls system pressure by opening automatically when internal pressure exceeds the preset 100 PSI limit in compatible HVAC systems. Featuring a 1-1/2-inch connection, it uses a calibrated spring mechanism to vent excess pressure and closes once normal operating conditions are restored. The valve is mounted at the specified pressure relief point on boilers or hydronic equipment with an appropriate discharge connection. Timely pressure release prevents excessive stress on the system and preserves the integrity of connected equipment during operation.
