Industrial Valves: Relief Valve Blowdown Rings; D/P
2013-5-7 · 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).
