Black and Decker Pressure Washer Parts

This is an authentic OEM part that has been sourced directly from DeVilbiss. The thermal relief valve is essential to the operation of a pressure washer; it regulates the amount of pressure in the line at any given time. When the pressure in the line reaches a certain level the relief valve opens and allowed the extra pressure to bleed out of the line. This helps eliminate the risk of dangerous pressure levels building up in the lines of your pressure washer. The thermal relief valve is a safety mechanism that prevents serious damage to you or your equipment. You will need basic hand tools to complete this installation.
