ENGLISH
the retract/extend forces in the cylinder. The resulting pressure in both cylinder ports
will be less than full line pressure, but should not be completely de-pressurized, either.
Results from the test procedure other than those listed above could indicate a valve
malfunction, or system leakage, e.g., line, fitting, or actuator seal leaks.
Failure of the internal valve elements to shift synchronously leads to a fault in the CC4
Series double valve. This could happen for a variety of reasons, such as:
• Defective piston seals,
• Main valve elements experiencing a switching delay due to dirt or resinous oil,
• Insufficient electrical signals to valve solenoids; suitable voltage not available,
• Receipt of signals at solenoids not synchronous,
• Pilot valves experiencing a switching delay due to damaged components, dirt, or
resinous oil,
• Excessive water build-up in the valve.
9. Disconnecting and Removal
Risk of injury due to disconnecting pressurized or live parts.
f Disconnecting a pneumatic component while the system is pressurized and/
or while electrical power is supplied can result in injury or death due to sudden
pressure release, unexpected movement, or electric shock.
f Isolate and lock out the electrical and pneumatic systems before disconnecting the
valve.

10. Technical Specifications

Design: Redundant, 4/3 Closed Center, Dual Poppet.
Mounting Type: Sub-base mounted.
Actuation: Solenoid pilot operated with spring return. Two solenoids per valve element
(4 total) – two for extending and two for retracting.
Pilot Solenoid: According to VDE 0580; Rated for continuous duty.
Enclosure Rating: According to DIN 400 50 IP 65.
Standard Voltages: 24 volts DC.
Power Consumption (each solenoid): 3.5 watts.
Electrical Connections: Three A-coded 5-pin, M12 receptacles; two for the
solenoids (male) and one for the sensors (female).
Mid-Position Sensors: 2 per valve. Hall-effect discreet (2): 100 mA.
Ambient Temperature: 40° to 120°F (4° to 50°C).
Medium Temperature: 40° to 175°F (4° to 80°C).
Flow Media: Compressed air according to ISO 8573-1 Class 7:4:4.
Pilot Supply: Internal or External.
Operating Pressure: With Internal Pilot Supply: 60 to 120 psig (4 to 8 bar).
With External Pilot Supply: 0 to 120 psig (0 to 8 bar).
Pilot Supply Pressure: 60 to 120 psig (4 to 8 bar). Pressure must be equal to or
greater than inlet pressure.
Static Pressure: 0 to 150 psig (0 to 10 bar).
Mounting Orientation: Any, but horizontally with solenoids on top is preferred.
Monitoring: Dynamic, cyclical, external with customer supplied equipment.
Monitoring should check state of both valve mid-position sensors with any and all
changes in state of valve control signals. See Integration Guide for more information.
Construction Material: Valve Body: Aluminum.
Poppet: Acetal and Stainless Steel.
Seals: Buna-N, HNBR.
Shock Test (based on DIN EN 60068-2-27):
• Acceleration: Consult ROSS.
• Shock duration: Consult ROSS.
• Shock waveform: Consult ROSS.
• Vibration test: (based on DIN EN 60068-2-6):
• Frequency: Consult ROSS.
• Amplitude: Consult ROSS.
B Value according to ISO 13849-1 and -2: See B
10D
library.
Maximum Cycle Rate: 3 Hz.
Sound Pressure Level [dB(A)]: Consult ROSS.
The sound pressure level is influenced by the individual systems used for reduction
of noise emissions. Use only silencers with exhaust flow capability greater than the
exhaust capability of the valve, do not restrict the valve exhaust. Use of the product
without the silencer is not recommended.
Minimum Operation Frequency: Once a month, to ensure proper function operation.
Maximum Recommended Allowable Discordance Time: 150 msec.
11. Disposal
Dispose of the valve in accordance with the applicable statutory regulations in your
country.
