Hydraulic fluid power -- Identification of valve ports, subplates, control devices and solenoids
This standard was last reviewed and confirmed in 2018. Therefore this version remains current.
Specifies rules for the identification. Applies in particular to valves which will be developed in future with two and three ports, where today's practice of marking valve ports is different. The identification rules apply to those ports which provide the connection between two valves or between a valve and a pipe.
