Series CL03-EV

Aventics Serie CL03-EV comprises compact single pneumatic valves designed for directional air control in industrial automation systems. These valves feature 3/2-way, 5/2-way, and 5/3-way configurations with 24VDC electrical actuation, operating through solenoid control mechanisms to precisely manage compressed air flow. Primary applications include pneumatic cylinder control in packaging machinery, automated assembly lines, material handling systems, and process automation equipment where reliable switching performance is critical. Industries utilizing CL03-EV valves include automotive manufacturing, food processing, pharmaceutical production, and general factory automation where ISO 8573-1 clean compressed air systems require dependable directional control components.

Selection of Aventics CL03-EV valves depends primarily on required flow path configuration and actuation method, with 3/2-way variants like R412021815 providing simple on-off control while 5/2-way models such as R412017963 enable double-acting cylinder operation. The series operates on 24VDC electrical supply with solenoid actuation, featuring different return spring mechanisms including SR spring return and DS double solenoid variants for maintained positioning. Port connection follows standard pneumatic threading with compact manifold-mountable design optimized for space-constrained installations. Operating pressure typically ranges from 2 to 10 bar with flow coefficients varying by valve size, making proper sizing critical for achieving required actuator speeds and force output in the target application.

Aventics CL03-EV pneumatic valves comply with ISO 8573-1 compressed air quality standards and meet IEC 61508 functional safety requirements for industrial automation applications. The electrical components conform to IEC 60204-1 safety standards for electrical equipment in machinery, while mechanical construction follows ISO 5599-1 interface dimensions for pneumatic valve mounting. CE marking ensures compliance with European Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU, with EMC compatibility meeting EN 61000 electromagnetic compatibility standards. Additionally, the valves satisfy ISO 14040 environmental management principles and are designed according to DIN ISO 1219 pneumatic circuit symbols for proper system documentation and maintenance procedures.

The primary distinction between Aventics CL03-EV variants lies in their flow path configuration and actuation method, with 3/2-way models like R412021815 providing three ports for simple directional control while 5/2-way variants such as R412017963 offer five ports enabling double-acting cylinder control with exhaust switching. Spring return versions designated SR automatically return to initial position when de-energized, whereas double solenoid DS models like R412017951 maintain their switched position until electrically commanded to change state. The 5/3-way variant R412017955 includes a center position that blocks all ports or creates specific flow patterns, providing enhanced control flexibility for applications requiring intermediate positioning or pressure holding capabilities during system cycling.

Aventics CL03-EV valves require 24VDC electrical supply with current consumption typically ranging from 0.8 to 1.2 amperes during switching operations and lower holding current for maintained positions. Installation follows ISO 5599-1 standard manifold mounting with M5 threaded ports for pneumatic connections, compatible with standard compressed air systems operating between 2-10 bar pressure range. The compact design allows direct manifold mounting or individual installation using appropriate fittings, with electrical connections via integrated cable or connector depending on model specification. System compatibility includes integration with PLC control systems through standard digital output modules, requiring proper electrical protection and EMC filtering according to IEC 61000 standards for reliable operation in industrial electromagnetic environments.

Aventics CL03-EV pneumatic valves feature IP65 ingress protection rating ensuring dust-tight construction with protection against low-pressure water jets from all directions, suitable for typical industrial environments. Operating temperature range extends from -10°C to +50°C ambient with compressed air media temperature limits following ISO 8573-1 specifications for industrial pneumatic systems. Maximum operating pressure reaches 10 bar with proof pressure testing at 15 bar, while minimum operating pressure starts at 2 bar for reliable valve switching performance. The electrical components meet insulation voltage requirements of 500V AC according to IEC 60664-1 standards, with surge protection capabilities designed for Category II overvoltage conditions typical in industrial control environments.

Aventics CL03-EV pneumatic valves typically achieve 10 million switching cycles under normal operating conditions with ISO 8573-1 Class 3 compressed air quality, requiring periodic inspection every 12 months or 2 million cycles whichever occurs first. Maintenance procedures include checking electrical connections for corrosion, verifying proper switching response times, and monitoring for external air leakage using soap solution or ultrasonic detection methods. Service life extends beyond 5 years in properly maintained systems with clean, lubricated compressed air supply, though solenoid coil replacement may be required after extended high-frequency operation or exposure to elevated temperatures approaching the 50°C maximum specification. Preventive maintenance should include filter replacement upstream according to ISO 8573-1 requirements and periodic system pressure testing to verify continued compliance with the 10 bar maximum operating pressure specification.
