Description
The Watts F121575 Pressure Relief Valve is a control part that automatically releases excess fluid flow from a piping or tank system once it reaches a set limit of 150 PSI, preventing overpressure conditions during operation within HVAC systems. It is built with a 2-inch NPT threaded connection for inline mounting on compatible pipelines and pressure vessels. The valve remains closed under normal operating pressure and opens when internal pressure exceeds the preset threshold, redirecting flow to a discharge outlet. It is commonly used in water heating, pumping, and industrial fluid systems where controlled pressure regulation is required for system stability.
