Mechanical accessories

ISO 5599-1

The mechanical accessories for Aventics ISO 5599-1 series 581 valves comprise valve bodies without cover for sizes 2, 3, and 4. Bodies are categorised by switching function: 5/3EC (V581-5/3EC-I_-A-X), 5/3CC (V581-5/3CC-I_-A-X), 5/3PC (V581-5/3PC-I_-A-X), 5/2DP (V581-5/2DP-I_-A-M / A-D / A-X), and 5/2SR (V581-5/2SR-I_-A-X). Valve bodies without cover are replacement parts for maintenance and repair when the base body is worn or damaged but the electrical connection hardware and coils are to be reused.

Switching functionSizesVariants
5/3 EC (exhaust centre)2, 3, 4A-X (standard)
5/3 CC (closed centre)2, 3, 4A-X (standard)
5/3 PC (pressure centre)2, 3, 4A-X (standard)
5/2 DP (single-pressure)2, 3, 4A-M, A-D, A-X
5/2 SR (spring-return)2, 3, 4A-X (standard)

When replacing a valve body without cover, the solenoid coils, cover, and electrical accessories are removed from the old body and transferred to the new one. The correct body is selected from the full type code of the valve being replaced. The I2/I3/I4 suffix denotes the nominal size; the letters after the hyphen (A-X, A-M, A-D) describe the spring arrangement and cover variant. Bodies without cover are not complete valves - coils and cover must be sourced separately or transferred from the old valve.

Typical applications: Maintenance of production plant with series 581 valves where only the body needs replacement; preventive maintenance with body replacement at a defined service interval; repair of valves with a mechanically damaged body but intact coil; stocking replacement bodies as fast-moving spares for the most frequently used sizes 3 and 4.

What are Aventics mechanical accessories for ISO 5599-1 valves and which industries use them?
Aventics mechanical accessories for ISO 5599-1 valves are precision-engineered valve bodies, covers, and control components designed for industrial pneumatic systems requiring standardized interface compatibility. These accessories include valve housings without covers like the V581 series, valve covers with or without pilot valve integration, and manual override devices for bistable operation. Primary applications span automotive manufacturing, packaging machinery, material handling systems, and process automation where reliable compressed air control at operating pressures up to 10 bar is essential. Industries utilizing these components include pharmaceutical production, food processing, semiconductor manufacturing, and general industrial automation where ISO 5599-1 compliance ensures interchangeability between different manufacturers' valve systems.
What are the key technical selection criteria for Aventics ISO 5599-1 mechanical accessories?
Selection of Aventics ISO 5599-1 mechanical accessories requires matching valve function designation, port configuration, and mounting interface to system requirements. The V581 series offers multiple configurations including 5/2 double pilot (5/2DP), 5/3 exhaust center (5/3EC), 5/3 closed center (5/3CC), and 5/3 pressure center (5/3PC) valve bodies with I2, I3, or I4 interface sizes corresponding to different flow capacities. Port configurations range from 2P22 to 4P configurations, while cover assemblies must match the specific pilot control method whether pneumatic, electrical, or manual override operation. Critical selection parameters include maximum operating pressure rating, media compatibility with compressed air or inert gases, ambient temperature range, and required response time for the specific automation application.
Which international standards and certifications apply to Aventics ISO 5599-1 mechanical accessories?
Aventics ISO 5599-1 mechanical accessories comply with ISO 5599-1:2001 standard defining pneumatic fluid power valve mounting interface dimensions and performance requirements for industrial automation applications. These components meet EN 60204-1 electrical safety requirements when integrated with solenoid actuators, while material specifications conform to ISO 8573 compressed air quality standards for contamination levels. Manufacturing quality systems follow ISO 9001:2015 certification ensuring consistent dimensional accuracy and surface finish requirements. Additional compliance includes ATEX directive 2014/34/EU for potentially explosive atmospheres when specified, RoHS directive 2011/65/EU for restricted substance compliance, and CE marking demonstrating conformity with applicable European Union harmonized standards for pressure equipment and electromagnetic compatibility.
What are the main differences between Aventics V581 valve body variants?
Aventics V581 valve body variants differ primarily in switching function, interface size, and port configuration affecting flow capacity and system integration requirements. The 5/2DP models like 5813600000 and 5814600000 provide double pilot operation for spring return functionality, while 5/3EC variants offer exhaust center position for cylinder floating applications and 5/3CC models maintain closed center for pressure holding. Interface designations I2, I3, and I4 correspond to mounting flange sizes with I4 providing highest flow rates up to 3000 l/min at 6 bar differential pressure. Port arrangements include standard 2P22 configuration for basic applications and extended port options for complex manifold systems, while the A-designation indicates aluminum construction with anodized surface treatment for corrosion resistance in industrial environments.
What are the installation requirements and system compatibility for Aventics ISO 5599-1 accessories?
Aventics ISO 5599-1 mechanical accessories require mounting on standardized interface surfaces with bolt circle dimensions conforming to ISO 5599-1 specifications, utilizing M5 or M6 socket head cap screws torqued to 8-12 Nm depending on interface size. System compatibility extends to all pneumatic components meeting ISO 5599-1 dimensional standards regardless of manufacturer, enabling retrofit applications and multi-vendor system integration. Port connections accommodate G1/8, G1/4, or G3/8 threaded fittings for compressed air supply and exhaust, while electrical connections on covers utilize standard M12 or DIN 43650 connectors rated IP65 for industrial environments. Installation requires clean compressed air supply filtered to ISO 8573-1 Class 7.4.4 or better, with maximum particle size 5 μm and pressure dew point at least 15°C below ambient temperature.
What safety ratings and operating conditions apply to Aventics ISO 5599-1 mechanical accessories?
Aventics ISO 5599-1 mechanical accessories operate safely within temperature range -20°C to +80°C ambient with maximum operating pressure 10 bar for standard configurations and proof pressure testing to 15 bar according to ISO 5599-1 requirements. Valve bodies and covers achieve IP65 ingress protection rating when properly assembled with O-ring seals, providing dust-tight enclosure and protection against water jets from any direction. Electrical components integrated in covers maintain IP67 rating at connector interfaces when mated with appropriate cable assemblies featuring proper sealing. Materials comply with RoHS directive restrictions while aluminum valve bodies resist corrosion in industrial atmospheres, and internal sealing components withstand compressed air media with maximum 50°C temperature and lubrication levels up to ISO 8573-1 Class 9 without performance degradation over design service life.
What maintenance schedule and service life expectations apply to Aventics ISO 5599-1 mechanical accessories?
Aventics ISO 5599-1 mechanical accessories require preventive maintenance every 12-18 months including O-ring seal inspection, torque verification of mounting bolts to specified 8-12 Nm values, and compressed air quality verification to ISO 8573-1 Class 7.4.4 standards. Service life typically exceeds 10 million switching cycles under normal operating conditions with clean compressed air at 6 bar working pressure and ambient temperatures between 10°C to 60°C. Critical inspection points include valve body sealing surfaces for wear or damage, cover assembly electrical connections for corrosion, and internal passages for contamination buildup that could affect switching response time. Replacement intervals for sealing components range from 2-5 years depending on operating pressure, cycling frequency, and air quality, while aluminum valve bodies maintain structural integrity throughout equipment lifecycle when operated within specified pressure and temperature limits.
