Boiler Pressure Relief Valve HVAC Hydronic Boiler …

The boiler pressure relief valve (PRV) is a safety valve designed to relieve an excessive build up of pressure inside the boiler. The is a pressure vessel designed to handle a safe amount of pressure. If the pressure were to build up beyond the safety limitations as set forth by the design specifications the boiler system needs a safe way to vent the pressure to prevent an explosion.
