Blowdown is the intentional relieving or venting of pressure off of a piping system or the equipment in it. Boilers, HRSG’s, and other petrochemical and power equipment need either continuous or periodic blow downs to remove impurities and corrosion scale from their interior surfaces.
Blowdown valves must function within a control system, which normally controls the timing of continuous or automated blowdown events. Other blowdown valves are manually controlled, and must remain closed and leak-free until the refinery experiences a turnaround or the power plant conducts its outage.
Blowdown service is typically demanding, and the valve must stand up to high temperature, a variety of corrosive/erosive liquids, and debris. CIRCOR Energy’s portfolio of valves can do all that and more.
