STANDARD SPECIFICATIONS: For valves on this page.
Pilot Solenoids: Two, rated for continuous duty.
Standard Voltages: 24, 48, 110, 220 volts AC, 50/60 Hz; 24 volts DC;
110 volts DC. For other voltages, consult ROSS.
Voltages at pressure switches must not exceed 250 volts.
Power Consumption:
SIze 4:
Each solenoid, 35 VA maximum in-rush, 22 VA holding
on 50 or 60 Hz; 14 watts nominal on DC.
SIze 8, 12, 30: Each solenoid, 87 VA maximum in-rush, 30 VA
holding on 50 or 60 Hz; 14 watts nominal on DC.
Electrical Connections: Uses cord-grip connectors at solenoids.
Order connectors separately (see accessories page 17).
Electrical Connection:
Connectors according to DIN 43650 A (ISO 4400), must be ordered
separately.
Ambient Temperature: 40° to 120°F (4° to 50°C).
Media Temperature: 40° to 175°F (4° to 80°C).
Flow Media: Filtered air; 5 micron recommended.
Inlet Pressure:
SIze 4:
40 to 150 psig (2.5 to 10 bar).
Pressure Range:
Size 8, 12, 30: 30 to 125 psig (2 to 8.5 bar).
Enclosure Rating: IP 65 according to IEC-Publication 144 and
DIN 40050, Sheet 1.
CAUTION: If the system must be reset, electrical signals to both
solenoids must be removed to prevent the machine from immediately
recycling and producing a potentially hazardous condition.
*Pressure Switches &
Monitoring:
Valves without pressure switches
must not be used to control clutch/
brake mechanisms on press
machinery. Valves with pressure
switches must be used in conjunction
with an external monitoring device
to assist with OSHA compliance
(Ref. 1910.217).
The valves on this page do not have
a built-in monitor, and must only be
used in conjunction with an external
monitoring system. Such monitoring
system must be capable of inhibiting
the operation of the valve and
associated machinery in the event
of a failure within the valve.
