Boiler Pressure Relief Valve | HVAC Hydronic Boiler Safety

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.

Industrial Valves: Relief Valve Blowdown Rings; D/P and

A: The blowdown ring on a relief valve is adjusted to set the reseat pressure of the valve. (The spring determines the pressure at which the PSV will lift, and the blowdown ring determines when it will reseat.) A two-blowdown ring design provides the ability to adjust this reset pressure very accurately, which is required for most ASME Section 1 application (boilers).
