Notes:

Maximum Pressure when used on saturated steam us 14 bar g. (203 psi g.)

Overpressure = Set pressure +10% (or 0.1 bar g., whichever is greater)

Blowdown Pressure (Gas & Steam) = Set pressure -15% (or 0.3 bar g., whichever is greater)

Blowdown Pressure (Liquid) = Set pressure -20% (or 0.6 bar g., whichever is greater)
