Series 840

Aventics Series 840 pneumatic valves are 4/2-way directional control valves engineered for precise pneumatic system control in industrial automation applications. These solenoid-operated valves feature double solenoid (DS) and single solenoid (OC) configurations with integrated LED status indicators for enhanced operational visibility. Manufacturing industries including automotive assembly, packaging machinery, material handling systems, and process automation rely on Series 840 valves for their robust construction and consistent switching performance. The valves support both direct and indirect mounting configurations with standardized connection patterns for seamless integration into existing pneumatic circuits.

Selection of Aventics Series 840 valves requires evaluating electrical supply specifications including 12VDC, 24VDC, 24VAC, 110VAC, and 230VAC options with corresponding part numbers like V840-4/2DS-DI04-024DC-03-LED for 24VDC operation. Port configuration determines fluid flow paths with DI04 and DA06 designations indicating different internal geometries and flow characteristics. LED indicator integration provides visual confirmation of valve energization status, critical for diagnostic purposes and system troubleshooting. Operating pressure range, media compatibility with compressed air and inert gases, and switching frequency requirements must align with specific application demands for optimal performance and service life.

Aventics Series 840 pneumatic valves comply with EN ISO 4414 standards for pneumatic fluid power systems safety requirements and general principles. The valves meet IEC 60529 specifications for ingress protection ratings ensuring reliable operation in industrial environments with dust and moisture exposure. CE marking confirms conformity with European Machinery Directive 2006/42/EC for pneumatic control components used in automated machinery. ATEX compliance may apply to specific Series 840 variants intended for explosive atmosphere applications, requiring verification of zone classification compatibility during selection. Manufacturing quality follows ISO 9001 standards with traceability documentation for critical applications requiring component certification.

Series 840 DS (Double Solenoid) variants like V840-4/2DS-DA06-024DC-03-LED feature two independent solenoid coils enabling bistable operation where the valve maintains its last switched position without continuous power consumption. OC (Single Solenoid) configurations such as V840-4/2OC-DA06-024DC-03 utilize one solenoid coil with spring return mechanism, requiring continuous energization to maintain the actuated position. DS variants provide memory function capability ideal for fail-safe applications where power interruption should not affect valve position, while OC types offer simpler control logic and lower power consumption for applications requiring defined rest positions. Both configurations support identical port patterns and mounting interfaces with DA06 and DI04 internal geometries determining flow characteristics and pressure drop performance.

Aventics Series 840 valves require standard ISO 5599-1 mounting patterns for direct installation onto pneumatic manifolds or individual mounting bases with M5 threaded port connections. System compatibility demands filtered compressed air at 1.5 to 10 bar operating pressure with -5°C to +60°C ambient temperature range for reliable solenoid operation. Electrical connections utilize industry-standard DIN 43650 solenoid connectors ensuring compatibility with existing pneumatic control systems and PLC outputs. Installation orientation flexibility allows mounting in any position while maintaining specified flow rates and switching characteristics, though vertical mounting with electrical connection upward prevents moisture accumulation in connector housings.

Aventics Series 840 pneumatic valves achieve IP65 ingress protection rating providing complete dust sealing and protection against water jets from any direction during high-pressure washdown procedures. Operating temperature range extends from -10°C to +60°C for pneumatic media with solenoid coils rated for continuous duty at maximum ambient temperature of +50°C. Maximum operating pressure specification of 10 bar ensures safe operation within typical pneumatic system parameters while maintaining consistent switching forces and response times. The valves incorporate built-in electrical isolation meeting IEC 60364 standards for industrial control circuits with 500VAC test voltage between coil and body ensuring operator safety during maintenance operations.

Aventics Series 840 pneumatic valves require quarterly inspection of LED indicators, electrical connections, and pneumatic fittings with annual replacement of seal kits in high-cycle applications exceeding 1 million operations per year. Normal service life expectancy ranges from 5 to 8 million switching cycles under standard operating conditions with filtered air at 6 bar pressure and 20°C ambient temperature. Preventive maintenance includes semi-annual verification of switching response times below 50 milliseconds and measurement of coil resistance values within manufacturer specifications for early detection of winding degradation. Critical applications require documented maintenance logs including cycle counters, pressure readings, and electrical parameter measurements to support predictive maintenance strategies and optimize replacement schedules based on actual operating conditions rather than arbitrary time intervals.
