Aquatrol 560-ED is a high-capacity safety pressure relief valve designed to protect steam boilers, piping lines, and vessels by venting at a preset pressure. The 560/570 family uses 1 in × 1 in NPT connections and a set pressure of 50 psi for this model, suitable for steam and air/gas service in demanding industrial systems. Constructed with a brass body and trim, the valve carries ASME Section I “UV” (steam) and ASME Section VIII “UV” (pressure vessels) certifications, along with CE and CRN approvals. Its operating range spans 0–250 psig and -20°F to 406°F, aligning with typical steam and hot-water applications.
