Overview

ISO 15218:2003 (Pneumatic fluid power - 3/2 solenoid valves - Mounting interface surfaces) specifies the geometric and surface requirements for mounting interfaces of 3/2 pneumatic solenoid valves. The standard covers four mounting sizes and defines the arrangement of flow passage holes, fixing holes and the sealing surface for valves intended for operation up to a maximum rated pressure of 1.6 MPa (16 bar). Its objective is to ensure mechanical interchangeability and reliable sealing across compliant valve designs.

Key Topics

• Mounting sizes: Interfaces are defined for widths of 10 mm, 15 mm, 22 mm and 30 mm. Sizes 10/15/22 share a common interface presentation; the 30 mm width has dedicated figures for two exhaust variants.
• Hole arrangement: Each interface includes three holes for flow passages and two holes for fixing screws, plus provisions for a sealing surface. The layout details are provided by the figures and table in the standard.
• Surface condition requirements:
  • Roughness: Ra = 1.6 µm (see ISO 4287 and ISO 1302 for surface-profile specifications).
  • Flatness: 0.05 mm maximum for sizes 10, 15 and 22; 0.1 mm maximum for size 30.
• Dimensional tolerances: General unspecified tolerances are to comply with ISO 2768-1. Specific dimensional values and tolerances for each size are given in the standard's figures and table.
• Variants for size 30: The 30 mm interface includes two variants shown in separate figures - one with a collectable exhaust or with a non-collectable exhaust - each with defined mounting and sealing provisions.
• Identification guidance: Manufacturers conforming to the standard are recommended to reference ISO 15218:2003 in documentation, test reports and catalogs to indicate compliance.

Applications

ISO 15218:2003 is aimed at designers, manufacturers and system integrators working with pneumatic control systems who require:

• Interchangeability of 3/2 solenoid valves across suppliers and products.
• Reliable sealing and mounting under pressures up to 1.6 MPa.
• Standardized interfaces for valve manifold blocks, actuator control manifolds and pneumatic control panels.

Adoption reduces design variations, simplifies inventory and supports modular system design in factory automation, process equipment and fluid power control systems.

Related Standards

The standard references and aligns with these ISO documents:

• ISO 1302 - surface texture indication in technical product documentation
• ISO 2768-1 - general tolerances for linear and angular dimensions
• ISO 4287 - surface texture: profile method and parameters
• ISO 5598 - vocabulary for hydraulic and pneumatic systems
• ISO 11727 - identification of ports and control mechanisms on valves

Keywords: ISO 15218, 3/2 solenoid valves, mounting interface surfaces, pneumatic, dimensions, tolerances, Ra 1.6 µm, 1.6 MPa, valve interchangeability.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur
publication comme Normes internationales requiert l'approbation de 75 % au moins des comités membres
votants.
L'attention est appelée sur le fait que certains des éléments du présent document peuvent faire l'objet de
droits de propriété intellectuelle ou de droits analogues. L'ISO ne saurait être tenue pour responsable de ne
pas avoir identifié de tels droits de propriété et averti de leur existence.
