Vaillant 178985 Pressure Relief Valve

Vaillant 178985 Pressure Relief Valve

The pressure relief valve or PRV is a safety instrument in place to reduce pressure that builds up within the heating system. Heating and cooling of water within a sealed system creates pressure fluctuations that could reach dangerous levels. A PRV has a tap and a fixed pressure allowance that when reached opens the tap to release water.
