Overview

ISO 10094-1:2021 - "Pneumatic fluid power - Electro‑pneumatic pressure control valves - Part 1" specifies the main characteristics that suppliers must include in product literature for electro‑pneumatic continuous pressure control valves. It covers electrically modulated proportional pressure valves, proportional valves without electronic pressure feedback, and proportional valves with electronic pressure feedback. The document is limited to components that exhaust to atmosphere and links to test methods in ISO 10094-2:2021.

Key topics and technical requirements

The standard defines which performance data and graphical characteristics suppliers should publish to help users select and apply electro‑pneumatic pressure control valves. Major topics include:

Electric characteristics
- Minimum required supply voltage, current and power.
Static characteristics
- Control signal / pressure characteristic at null flow (graphical characteristic line with sensitivity and offset).
- Linearity and hysteresis expressed as % full scale.
- Minimum regulated pressure, resolution, repeatability, sensitivity (Pa/V, Pa/mA or Pa/numerical signal), and offset.
- Flow / pressure characteristics (regulated pressure vs forward or relief flow for specified inlet pressures).
- Pressure regulation characteristic (variation of regulated pressure with inlet pressure at defined flow).
- Maximum leakage flow at null forward or relief flow.
Dynamic characteristics
- Charge and discharge response behaviour and optional frequency response data (frequency response reporting is now optional in the 2021 edition).
Symbols, units and identification
- Standardized symbols and units (per ISO conventions) and a required identification statement referencing ISO 10094-1.
Referenced test methods
- Where tests are required, ISO 10094-2:2021 is the normative test-methods reference.

Note: This second edition (2021) introduced scope clarifications, revised figures, added sensitivity and offset definitions, and made frequency-response data optional.

Applications and users

This standard is practical for:

Manufacturers and suppliers preparing datasheets and technical literature for electro‑pneumatic pressure control valves.
Design and control engineers specifying components for pneumatic control, pressure tracking, or pressure regulation systems.
Procurement and quality teams evaluating vendor claims and comparing valve performance.
Test labs and R&D groups using ISO 10094-2 test methods to verify supplier data.

Typical applications include pneumatic pressure regulation, closed‑loop pressure control, laboratory instrumentation, process automation and motion control where precise pressure tracking is required.
