Scope

This standard specifies the identification and labeling rules for the air ports of pneumatic directional control valves. The air ports include the main air circuit connection port, the control air circuit connection port and the pilot air circuit connection port. This standard applies to the identification and labeling rules for electromagnetic coil connecting wires. However, it does not apply to the internal electrical connection of integrated components, such as the connection of bus control systems. This standard specifies the identification and labeling rules for the control mechanism of directional control valves. This standard specifies the identification and labeling rules for the air ports and (or) flow directions of filters, pressure reducing valves, lubricators, check valves, flow control valves and other auxiliary components. This standard does not include the air port identification and labeling rules for pneumatic proportional control valves, pneumatic logic valves, cylinders, air motors, swing cylinders, air compressors, air dryers or other components not specifically stated in this standard.
