Overview

This document provides detailed technical specifications, product indexing, and coil characteristics for direct operated solenoid pilot valves, solenoid air operated poppet valves, and spool valves used in pneumatic systems.

1. Valve Types and Functions

The valves are categorized primarily by their function and port/position configurations, including 2/2, 3/2, 4/2, 5/2, and 5/3 valve types. Functions include normally closed (NC), normally open (NO), and various pilot-operated configurations.

Port and Connection Types

• Instant fittings identified by outer diameter (O.D.) in mm.
• Internal thread connections denoted by ØG.
• Pad mounts with variations: standard pad mount (n), pneumatic-electric pad mount (:), CNOMO size 15 (s), CNOMO size 30 (t), and NAMUR mounting pad (,).

Valve Technology

• Rubber packed valves for sealing.
• Stainless steel screws for durability.

2. Performance Parameters

• Maximum pressure: Ranges typically from 8 to 16 bar depending on valve series.
• Flow rates at 6 bar: Vary widely from approximately 0.08 l/min to over 6300 l/min (ANR), depending on valve size and type.
• Kv coefficients: Provided for flow characterization, ranging from 0.086 to 7.0 and above.

3. Product Series and Illustrations

Each valve type is associated with a series number and page reference for detailed illustrations and further technical data. Examples include:

• Micro series (e.g., P501A, P501B) for small flow applications.
• High flow series (e.g., P502A, P502B).
• Piezotronic series (e.g., P503).
• Banjo and CNOMO pad mount series (e.g., P508, P509, P510).
• Spool valves and poppet valves with integrated pilot options (e.g., P545, P550, P559).

4. Standards and Compliance

The valves comply with international standards such as ISO 5599-1 and VDMA/ISO 15407 series. The document notes that availability, design, and specifications are subject to change without notice.

5. Coil Characteristics and Replacement

Coils are designed for continuous duty operation within specified voltage tolerances (±10-15% of nominal voltage) and ambient temperature limits, complying with IEC 335, EN 60730-1, and UL 429 standards.

Coil Types and Catalog Numbers

Coils are available for both alternating current (AC, 50 Hz) and direct current (DC) with various voltage ratings (12V, 24V, 48V, 110V, 115V, 230V, 240V). Examples include:

• C22A and CM22 series coils for series 189 valves.
• CM22-4W/6.9W and CM25-5W/6.9W coils for series 356 valves.
• C25A and C30A coils for series 190 and 192 valves.

Specialized coils for high reliability in humid exterior environments are also available.

6. Additional Notes

• Connectors and accessories are referenced in a separate section (section J).
• All leaflets and detailed product information are available on the manufacturer's website: www.asconumatics.eu.

Summary of Critical Information

• Valve selection depends on required function, port configuration, connection type, maximum pressure, and flow rate.
• Pad mount options allow integration with pneumatic-electric systems and compliance with CNOMO and NAMUR standards.
• Coil compatibility must be matched to valve series and voltage requirements for reliable operation.
• Material and sealing choices (rubber packed, stainless steel screws) ensure durability and environmental resistance.
