Valve systems

Aventics valve systems are modular pneumatic control platforms that integrate directional valves, manifolds, and electronic controls into unified assemblies for precise compressed air distribution and machine automation. These systems like the VTS (Ventilträgersystem) and MVS (Modulares Ventilsystem) are extensively deployed in automotive assembly lines for actuator sequencing, packaging machinery for product handling, and general industrial automation where multiple pneumatic cylinders require coordinated control. The modular architecture allows engineers to configure valve islands with up to 32 valve positions on a single manifold, operating at standard industrial pressures from 2 to 10 bar with response times under 10 milliseconds for high-speed production requirements.

Engineers must evaluate operating pressure requirements typically ranging from 2 to 10 bar, flow capacity measured in Nl/min at 6 bar supply pressure, and electrical interface specifications including 24V DC control voltage for solenoid actuation. Port configuration is critical, with standard options including M5 pneumatic connections for compact applications and G1/8 threaded ports for higher flow requirements, while valve function types range from 3/2-way for single-acting cylinders to 5/2-way for double-acting applications. The VTS systems accommodate different actuator sizes and cycle frequencies, with electronic diagnostic capabilities enabling predictive maintenance through integrated pressure monitoring and valve position feedback sensors.

Aventics valve systems comply with ISO 5599-1 for valve mounting interface dimensions ensuring interchangeability, while electrical components meet IEC 61131-2 standards for industrial automation environments and electromagnetic compatibility requirements. The systems typically achieve IP65 protection rating for dust and water ingress resistance, with ATEX certification available for explosive atmosphere applications in chemical and petrochemical industries where Zone 1 and Zone 2 classifications are required. CE marking confirms compliance with European Machinery Directive 2006/42/EC, and many models meet UL recognition for North American installations, ensuring global deployment capability across diverse industrial sectors and regulatory environments.

The VTS (Ventilträgersystem) represents Aventics' traditional valve carrier system with fixed manifold blocks accommodating up to 16 valve positions, designed for established applications requiring proven reliability and straightforward maintenance access. The MVS (Modulares Ventilsystem) offers enhanced modularity with snap-together manifold segments enabling field reconfiguration, integrated electronics with IO-Link communication capability, and reduced installation space requirements through vertical stacking configurations. VTS systems excel in heavy-duty applications with robust aluminum manifolds rated for continuous operation, while MVS provides superior diagnostic functionality including individual valve monitoring, pressure sensing at each station, and network-based status reporting for Industry 4.0 integration requirements.

Aventics valve systems require clean, dry compressed air supply filtered to ISO 8573-1 Class 7:4:4 with maximum particle size of 40 microns and dew point at least 10°C below minimum operating temperature to prevent valve malfunction. Standard DIN rail mounting accommodates most valve carriers, while larger manifolds utilize aluminum profile mounting with M6 threaded connections spaced at 50mm intervals for mechanical stability. Electrical installation demands 24V DC supply with maximum 2A current draw per valve position, and communication interfaces support standard fieldbus protocols including Profibus DP, DeviceNet, and Ethernet/IP for seamless integration with existing PLC systems and industrial networks.

Aventics valve systems operate reliably within temperature ranges from -10°C to +60°C ambient conditions, with working pressure capabilities from 2 to 10 bar and maximum proof pressure of 15 bar for system integrity verification. Standard models achieve IP65 protection rating against dust ingress and water jets, while specialized variants reach IP67 for wash-down applications in food processing and pharmaceutical manufacturing environments. Safety-rated versions meet Performance Level PLd according to ISO 13849-1 for safety-critical applications, incorporating dual-channel valve monitoring and forced-guided contacts that ensure fail-safe operation during emergency stop sequences, with maximum switching frequency of 5 Hz for standard solenoid valves and up to 20 Hz for high-speed variants.

Aventics valve systems require quarterly inspection of air filter elements and annual lubrication of moving manifold components, with solenoid valves typically achieving 10 million switching cycles at rated pressure and temperature conditions before requiring replacement. Preventive maintenance includes monthly verification of supply air quality to ISO 8573-1 standards, semi-annual electrical connection torque checks to 0.8 Nm for terminal blocks, and annual calibration of integrated pressure sensors to maintain ±0.1 bar accuracy throughout the operating range. Expected service life reaches 15 years for manifold assemblies under normal industrial conditions, while electronic components typically require replacement after 8-10 years of continuous operation, with diagnostic systems providing advance warning of component degradation through trend monitoring of response times and leakage rates.
