Valves and valve systems

Aventics valves and valve systems are precision-engineered pneumatic control components designed for industrial automation applications across manufacturing, packaging, automotive, and process industries. These systems include directional control valves like the CL03-EV series 3/2-way and 5/2-way configurations, electro-pneumatic pressure regulators, and integrated fieldbus modules for distributed control architectures. The product range encompasses individual solenoid valves operating at 24VDC, complete valve manifold systems with integrated I/O functionality, and communication interfaces supporting PROFINET, EtherNet/IP, and CANopen protocols for seamless integration into modern factory automation networks.

Selection of Aventics pneumatic valves requires evaluation of operating pressure range typically 0-10 bar for standard applications, port connection sizes from G1/8 to G1/2 threading, and flow coefficient values determining air consumption rates. The CL03-EV series offers 24VDC solenoid operation with response times under 10 milliseconds for high-frequency switching applications. Valve function specification includes 3/2-way normally closed or open configurations for simple on-off control, 5/2-way double-acting cylinder control with spring return or detent positions, and 5/3-way center exhaust options for safety positioning. Media compatibility extends to compressed air quality per ISO 8573-1 class 7:4:4 with operating temperatures from -10°C to +60°C ambient.

Aventics valve systems comply with ISO 5599-1 for mounting interface dimensions ensuring interchangeability with other manufacturers, ISO 4414 for pneumatic system safety requirements, and IEC 60529 IP rating classifications for environmental protection. The fieldbus modules like the DDL and AES series meet IEC 61131 programmable controller standards and carry CE marking per EU Machinery Directive 2006/42/EC. ATEX certification applies to explosion-proof variants for Zone 1 and Zone 2 hazardous area installations, while food-grade applications require compliance with FDA 21 CFR 177 material regulations. EMC compatibility follows EN 61000 series standards for industrial electromagnetic environments with immunity levels per IEC 61326-3-1.

The Aventics CL03-EV series represents compact individual solenoid valves with direct 24VDC electrical connection for simple point-to-point wiring, offering 3/2-way and 5/2-way configurations with integrated manual override and LED status indication. In contrast, DDL fieldbus modules like the R412000732 provide distributed I/O functionality with Ethernet communication, supporting up to 32 valve positions per module with diagnostic capabilities and remote configuration through web-based interfaces. The CL03-EV valves mount directly onto manifold blocks with sub-base connections, while DDL systems integrate complete valve manifolds with embedded controllers, reducing cabinet wiring by up to 80% compared to traditional hardwired installations.

Aventics valve installations require compressed air supply filtered to ISO 8573-1 class 7:4:4 with pressure regulation maintaining ±2% stability and supply voltage tolerance of 24VDC ±10% for reliable solenoid operation. Manifold mounting follows ISO 5599-1 standard with M5 threaded connections and 15mm center-to-center spacing for valve positions. Fieldbus modules like the CMS-B series require Ethernet infrastructure with managed switches supporting Quality of Service protocols and dedicated VLAN segmentation for deterministic communication timing. Installation ambient temperature range spans -5°C to +50°C with maximum 95% relative humidity non-condensing, while vibration resistance meets IEC 60068-2-6 with 2g acceleration at 57Hz frequency for mobile machinery applications.

Aventics valve systems achieve IP65 protection rating per IEC 60529 ensuring complete dust ingress protection and water jet resistance for washdown environments, with electrical connections rated IP67 when properly mated. Operating temperature range extends from -10°C to +60°C for standard valves with extended variants handling -20°C to +80°C in specialized applications. Working pressure specifications cover 0.5 bar minimum to 10 bar maximum with burst pressure testing at 4x rated pressure per ISO 4414 safety factors. The valve housings utilize anodized aluminum construction with NBR seals providing ozone resistance per DIN 53509, while solenoid coils feature Class F insulation rated for 155°C continuous operation with 40% duty cycle capability for high-frequency switching applications.

Aventics pneumatic valves require quarterly inspection of air supply quality per ISO 8573-1 standards with filter element replacement and condensate drainage to prevent contamination-induced failures. Standard valve service life exceeds 20 million switching cycles for the CL03-EV series under rated conditions with annual seal kit replacement recommended in continuous duty applications. Preventive maintenance includes six-monthly leak testing at 1.5x operating pressure, solenoid coil resistance measurement maintaining 10-15% of nameplate values, and manual override function verification. Fieldbus module diagnostics provide real-time monitoring of valve response times with automatic alerts when switching times exceed 15 milliseconds indicating seal degradation, while embedded wear counters track cumulative cycles enabling predictive maintenance scheduling before reaching 80% of rated service life.
