Full title and description

ISO 10094-1:2021 — Pneumatic fluid power — Electro-pneumatic pressure control valves — Part 1: Main characteristics to include in the supplier's literature. This part defines the essential characteristics that suppliers should publish for electro‑pneumatic continuous pressure control valves to allow correct selection and comparison.

Abstract

This document specifies which characteristics of electro‑pneumatic continuous pressure control valves are to be included in the supplier’s literature. It addresses electrically modulated pneumatic proportional pressure valves, proportional pressure control valves without electronic pressure feedback and proportional pressure control valves with electronic pressure feedback, limited to components with an exhaust port vented to atmosphere. Notes reference related documents for non‑electrically modulated valves and electro‑pneumatic continuous flow control valves.

General information

Scope

ISO 10094-1:2021 defines the principal characteristics (performance, electrical and pneumatic interfaces, materials/temperature limits, dynamic behaviour descriptors, and information presentation) that shall appear in supplier literature so users can select, compare and apply electro‑pneumatic continuous pressure control valves. The scope is restricted to devices with an exhaust port vented to atmosphere and excludes non‑electrically modulated valves (see ISO 6953‑1) and electro‑pneumatic continuous flow control valves (see ISO 10041‑1).

Key topics and requirements

• List of main characteristics to be reported in supplier literature (e.g., nominal and maximum supply pressure, control signal type and range, supply/exhaust port designations, flow/pressure characteristics, dead band, hysteresis, resolution and response time).
• Definitions and terminology aligned with ISO 5598 for pneumatic control components.
• Classification of types covered: electrically modulated proportional pressure valves, proportional valves with and without electronic pressure feedback.
• Limitations: components with exhaust port to atmosphere; tests and test presentation are covered in the companion Part 2.
• Guidance on presentation format to improve comparability between manufacturers’ data sheets.

Typical use and users

Primary users include valve and actuator manufacturers, pneumatic system designers, component specification engineers, test laboratories, procurement specialists and maintenance teams who need standardized supplier information to compare performance, ensure compatibility and support safe, efficient selection and application of electro‑pneumatic pressure control valves.

Related standards

ISO 10094-1:2021 is part of a two‑part set where ISO 10094-2:2021 specifies the test methods to determine the characteristics required in Part 1. The document also references ISO 5598 (terminology), ISO 6953‑1 (characteristics of non‑electrically modulated pneumatic pressure control valves) and ISO 10041‑1 (electro‑pneumatic continuous flow control valves) as related guidance.

FAQ

Q: What is this standard?

A: ISO 10094-1:2021 is an International Standard that specifies the main characteristics suppliers should include in literature for electro‑pneumatic continuous pressure control valves to allow correct selection and comparison.

Q: What does it cover?

A: It covers the list and definition of characteristics to be reported (performance, interfaces, dynamic behaviour, environmental limits, etc.) for valves vented to atmosphere and identifies what is excluded and which complementary documents to consult for testing and other valve types.

Q: Who typically uses it?

A: Manufacturers, design and application engineers, test labs, procurement and maintenance professionals working with pneumatic control systems and electro‑pneumatic valves.

Q: Is it current or superseded?

A: ISO 10094-1:2021 (Edition 2) is the current published version (published November 2021) and it supersedes ISO 10094-1:2010 (withdrawn).

Q: Is it part of a series?

A: Yes — it is Part 1 of the ISO 10094 series; Part 2 (ISO 10094-2:2021) defines the test methods used to determine the characteristics required by Part 1.
