Sumary

Pneumatic fluid power. Identification of ports and control mechanisms of control valves and other components.

1.1 This International Standard includes rules for identifying and marking ports in pneumatic directional control

valves. These ports are the main flow connections, control connections and pilot supply connections.

1.2 This International Standard includes rules for identifying and marking electrical leads for solenoids. It is not

applicable to internal electrical connections across manifold sections, such as connections to bus systems.

1.3 This International Standard includes rules for identifying and marking control mechanisms of directional control

valves.

1.4 This International Standard includes rules for identifying and marking ports and/or flow path directions in filters,

regulators, lubricators, non-return (check) valves, flow control valves and other ancillary devices.

1.5 This International Standard does not include rules for identifying and marking ports on proportional pneumatic

valves, air logic valves, cylinders, air motors, semi-rotary actuators, air compressors, air dryers or other devices not

specifically described in this International Standard.

ZOOM ON ... the Requirements department

To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
