ISO Symbol
Solenoid operated
Technical Data
Fluid: Compressed air
Maximum Pressure: 16 bar (240 psig)
Minimum Operating Pressure: 3 bar (45 psig)
Operating Temperature: -20°C to 50°C
(Solenoid rating max is 50°C whilst unit max is 80°C. Consult our technical service
below +2°C)
Gauge Ports: Rc1/8
Exhaust Ports: ISO G1/2 with ISO G and Rc main ports,
1/2“ PTF with PTF main ports
Typical flow with 6,3 bar (90psig) inlet pressure and
outlet pressure drop of 0,5 var (7 psig)
57dm
3
/s (120 scfm) (P1 to P2 = Cv 4.2) (P2 to P3 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.

Warning
These products are intended for use in industrial compressed air
systems only. Do not use these products where pressures and
temperatures can exceed those listed under ‘Technical Data’.
Before using these products with fluids other than those specified, for
non-industrial applications, life-support systems, or other applications not
within published specifications, consult NORGREN.
Through misuse, age, or malfunction, components used in fluid
power systems can fail in various modes. The system designer is warned
to consider the failure modes of all component parts used in fluid power
systems and to provide adequate safeguards to prevent personal injury or
damage to equipment in the event of such failure.
System designers must provide a warning to end users in the
system instructional manual if protection against a failure mode
cannot be adequately provided.
System designers and end users are cautioned to review specific
warnings found in instruction sheets packed and shipped with these
products.
Water vapor will pass through these units and will condense into
liquid if air temperature drops in the downstream system. Install an air
dryer if water condensation could have a detrimental effect on the
application.
