9.0 RATING PLATE DATA
The user is obliged to keep the marking of the valve clearly visible: any coatings or paintwork performed on the product that
make the valve unidentifiable are not to be attributed to the manufacturer.
The rating plate data (see example provided here) includes the following:
• Manufacturer’s name/logo and address (possible distributor name/logo)
• Mod.: = device name/model followed by the connection diameter
• CE-51CM4100 = certification pin number
• Cl. A =
Seal strength in counterflow at 150 mbar in accordance with EN 161
• Gr. 2 = Mechanical resistance group 2 in accordance with EN 161
• EN 161 = Product reference regulation
• P.max = Maximum pressure at which product operation is guaranteed
• IP.... = Protection rating
• 230V.... = Power supply voltage, frequency (if Vac), followed by electrical absorption
Example of electrical absorption indication: 89/25 VA indicates 89 VA at start, 25 VA at steady state
• TS = Temperature range within which product operation is guaranteed
• = Conformity with Regulation (EU) 2016/426 followed by Notified Body No.
• = In compliance with ATEX followed by the protection mode
(complete protection mode indicated on coil and CPI switch)
• year = Year of manufacture
• Lot = Product serial number (see explanation below)
• U1804 = Lot issued in year 2018 in the 4th week
• 2185 = progressive job order number for the indicated year
• 00001 = progressive number referring to the quantity of the lot
