This document specifies which characteristics of electro-pneumatic continuous pressure control valves are to be included in the supplier's literature.

In accordance with ISO 5598, these control valves include:

—    electrically modulated pneumatic proportional pressure valves,

—    proportional pressure control valves without electronic pressure feedback, and

—    proportional pressure control valves with electronic pressure feedback.

This document is limited to the characterization of components with an exhaust port to the atmosphere.

NOTE 1   The characteristics of non-electrically modulated pneumatic pressure control valves are specified in ISO 6953‑1.

NOTE 2   The characteristics of electro-pneumatic continuous flow control valves are specified in ISO 10041‑1.
