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.
