DN50 LGS HI-FLOW Relief Valve H3650A1F26

50mm Nominal Bore Single Trim Enclosed Discharge Relief Valve for Liquid, Gas and Steam

Notes:

Maximum Pressure when used on Saturated Steam is 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)
