Pressure Vacuum Orifice siz es Leak rate2, 3 R esp o n se HFPRO7... 0...50 psid 0...27 "Hg (0...915 mbar) 0.070" (1.8 mm) ≤0.5 sccm of nitrogen at 1 and 10 psi <30 msec cycling FLOW CURVES4 Notes: 2. Low differential pressure represents the worst case condition due to the reverse flow (pressure-assist) nature of the valve. 3. sccm denotes Standard Cubic Centimeters per Minute. It is a unit for the flow rate at standard conditions of temperature and pressure. 1000 sccm = 1 slpm. 4. slpm denotes Standard Liters per Minute. It is a unit for the flow rate at standard conditions of temperature and pressure. 1 slpm = 1000 sccm.
