Series LS04

The Aventics LS04 series comprises compact individual pneumatic valves engineered for precise directional control in automated manufacturing systems. These valves find primary application in automotive assembly lines, packaging machinery, and material handling equipment where rapid switching between pneumatic circuits is required. The series includes both 3/2-way and 5/3-way configurations operating at 24VDC, making them suitable for PLC-controlled automation systems across industries requiring reliable compressed air distribution and cylinder actuation.

Aventics LS04 valve selection requires evaluating the valve function designation where 3/2-way models like R422103590 provide basic switching while 5/3-way variants such as R422103843 enable complex cylinder positioning. All models operate on 24VDC electrical supply with M8 connector interface and feature either D4 or D6 port configurations for different flow requirements. The -AF suffix indicates these valves incorporate pneumatic actuation with manual override capability, while the switching functions include normally open (OO), normally closed (CC), and changeover (CO) configurations to match specific application logic requirements.

Aventics LS04 series valves comply with ISO 5599-1 standards for pneumatic valve mounting interfaces and DIN EN 175301-803 specifications for M8 electrical connector requirements. These valves meet CE marking requirements under the Machinery Directive 2006/42/EC and are designed according to ISO 4414 pneumatic system safety standards. The series also conforms to IEC 60529 ingress protection ratings and follows VDMA 24562 guidelines for pneumatic component reliability testing, ensuring compatibility with European industrial automation standards and facilitating integration into compliant pneumatic systems.

The Aventics LS04 series differentiates primarily through valve function types where 3/2-way models like R422103573 provide two-position switching while 5/3-way versions such as R422103842 enable three-position control with center exhaust capability. Port size variations include D4 and D6 configurations affecting flow capacity, with D6 models offering higher throughput for larger actuators. Switching logic varies between normally open (OO designation), normally closed (CC designation), and changeover (CO designation) functions, while all variants maintain the same 24VDC electrical interface and M8 connector standard for consistent system integration.

Aventics LS04 valves require standard ISO 5599-1 mounting patterns for secure mechanical installation and feature M8 4-pin connectors for 24VDC electrical supply connection. The valves accommodate compressed air media with maximum particle size filtration to 40 micrometers and require inlet pressure regulation between 2 and 10 bar operating range. Port connections utilize standardized pneumatic fittings compatible with 4mm and 6mm tubing depending on the D4 or D6 model specification, while proper electrical grounding through the mounting base ensures reliable solenoid operation and electromagnetic compatibility in industrial control panels.

Aventics LS04 valves achieve IP65 ingress protection rating providing dust-tight sealing and protection against water jets from any direction, suitable for typical industrial environments. Operating temperature range spans -10°C to +50°C ambient conditions while maintaining full switching performance across working pressure range of 2 to 10 bar gauge pressure. The valves incorporate fail-safe design with spring return actuation ensuring predictable valve state during power loss conditions, and the 24VDC electrical rating provides safe extra-low voltage operation compliant with industrial safety regulations for automated machinery integration.

Aventics LS04 valves require preventive maintenance inspection every 2 million switching cycles or annually under continuous duty applications, focusing on electrical connector integrity and pneumatic seal condition. Expected service life reaches 10 million switching cycles when operated within specified pressure and temperature ranges with properly filtered compressed air supply. Regular maintenance includes verification of switching response time under 10 milliseconds and checking coil resistance values against factory specifications, while replacement of internal sealing elements should occur every 5 years or when leakage exceeds 0.1 l/min at 6 bar test pressure to maintain system efficiency and prevent contamination of downstream pneumatic components.
