Typical flow with 6,3 bar (90psig) inlet pressure and
outlet pressure drop of 0,5 var (7 psig)
57dm
3 /s (120 scfm) (P 1 to P 2 = Cv 4.2) (P 2 to P 3 Cv = 5.6)
Snap pressure: Full flow when downstream pressure reaches
35% - 60% of inlet pressure
Charge time: For 2 litre downstream volume and inlet pressure of
6,3 bar (90 psig), 0,2s minimum, 75 secs. maximum
Solenoid operator
22 mm, 24V DC, 2W only (no manual overide)
Soft start valves allow a controlled increase of
pressure onto downstream cylinders / machines
offering protection to personnel equipment.
The positively driven micro switch ensures a
monitored dump function.
Note: Turn on system air supply prior to applying
signal to operator. Failure to do so may cause valve to
continuously exhaust.
