Single valves

Aventics single valves are individual pneumatic directional control valves that manage compressed air flow in automated systems, available in 3/2-way, 5/2-way, and 5/3-way configurations from series CL03-EV, CD12, and 567. These valves serve as fundamental control elements in manufacturing automation, packaging machinery, automotive assembly lines, and material handling systems where precise air flow direction and timing are critical. Industrial applications include actuator control in pick-and-place operations, cylinder positioning systems, and pneumatic tool activation across sectors demanding reliable compressed air management at operating pressures typically ranging from 2 to 10 bar.

Selection of Aventics single valves depends primarily on flow function with 3/2-way valves like the 567 series providing basic on-off control, 5/2-way valves such as the CL03-EV series R412017963 enabling double-acting cylinder control, and 5/3-way CD12 series valves offering neutral center positions for complex control sequences. Operating voltage requirements typically include 24V DC options as seen in CL03-EV models, while port connection sizes range from G1/8 to G1/2 depending on application flow requirements. Critical selection factors include maximum operating pressure up to 16 bar for most series, switching frequency capabilities up to 10 Hz, and response times typically under 50 milliseconds for industrial automation applications.

Aventics single valves comply with ISO 5599-1 for pneumatic valve interface standards ensuring interchangeable mounting patterns and port configurations across industrial applications. The valves meet EN 60204-1 electrical safety requirements for machine control circuits and ISO 4414 pneumatic system safety standards for compressed air installations. ATEX certification applies to specific models designed for explosive atmosphere applications in chemical processing and mining environments, while CE marking confirms conformity with European machinery directives. Installation must follow ISO 14121-1 risk assessment protocols and maintain compliance with local pressure equipment directives for systems exceeding 0.5 bar operating pressure.

The CL03-EV series like model R412017963 represents compact solenoid valves with 24V DC operation designed for high-frequency switching applications up to 10 Hz, while the CD12 series such as model 5725655980 offers larger flow capacities with 5/3-way functionality for complex control sequences requiring neutral center positions. Series 567 valves including model 5673011340 provide economical 3/2-way directional control with manual override options for basic pneumatic circuits. Key distinctions include the CL03-EV series featuring sub-base mounting for easy maintenance access, CD12 series incorporating integrated flow control options, and 567 series offering direct mounting configurations for space-constrained installations with operating pressures from 2 to 8 bar.

Aventics single valves require clean, dry compressed air meeting ISO 8573-1 quality class 7:4:4 with maximum particle size 40 micrometers and pressure dew point -10°C to prevent internal contamination and ensure reliable operation. Installation demands proper sub-base mounting for CL03-EV series or direct manifold connection for CD12 series, with G1/8 to G1/2 port threads depending on model specifications and flow requirements up to 1000 l/min. System compatibility includes 24V DC control voltage for solenoid activation, protective circuitry against voltage spikes, and integration with PLC systems through standard digital outputs. Proper filtration, regulation, and lubrication units upstream ensure optimal valve performance and extend service life beyond 10 million switching cycles.

Aventics single valves typically achieve IP65 protection rating ensuring dust-tight sealing and protection against water jets from any direction, making them suitable for industrial environments with washdown requirements and outdoor installations. Operating temperature ranges span -20°C to +80°C for standard models, while pressure ratings extend from 2 to 16 bar depending on valve series and size configuration. The CL03-EV series maintains switching reliability at temperatures down to -10°C with response times under 20 milliseconds, while CD12 series valves handle higher flow rates up to 2000 l/min at maximum operating pressures. Safety considerations include fail-safe spring return options for critical applications and electrical isolation rated for 500V AC test voltage to prevent hazardous potential transfer.

Aventics single valves require quarterly inspection of air quality upstream including filter element replacement and moisture separator drainage to maintain ISO 8573-1 class 7:4:4 compressed air standards preventing premature seal wear and valve malfunction. Preventive maintenance includes annual solenoid coil resistance measurement expecting 50-150 ohm readings depending on model specifications, visual inspection for port leakage using soap solution testing, and verification of switching response times remaining under 50 milliseconds. Service life typically exceeds 10 million switching cycles for CL03-EV series under normal operating conditions with proper air treatment, while CD12 and 567 series achieve 5-8 million cycles depending on switching frequency and pressure differential. Critical applications require backup valve installation and predictive monitoring through cycle counting to schedule replacement before failure occurs.
