Marking
The motorised regulating valve is marked with two labels.
The rating label for the complete device (valve block) is located on the lower
left side. The upper line gives the device specification key "SYST-0258", while
the lower line gives the identity number and the encoded date of
manufacture.
Every drive also has its own rating plate with the following content:
• Specification key/Drawing No. e.g.: 0258-G665-205-00,
• Voltage and type of voltage: 24 V DC,
• Power consumption: e.g. 3.0 W,
• Rotation angle: e.g.: 28 s / 180°,
• Rated pressure: e.g.: 0 ... 2.5 bar,
• Identity number and the encrypted date of construction.
