For INLET Pressures other than 100 PSIG


Maximum Inlet Flow (-40° F/C PDP) = INLET Flow (above) x INLET Flow Factor (A) @ Actual Pressure (below)

Maximum Inlet Flow (-100°F/-73°C PDP) = INLET Flow (above) x INLET Flow Factor (B) @ Actual Pressure (below)

Purge Flow = PURGE Flow (above) x PURGE Flow Factor (C) @ Actual Pressure (below)

Rated OUTLET Flow = Calculated Maximum Inlet Flow - Calculated Purge Flow
