Note! With the L15 / L17 execution for ambient temperatures Nominal power 15 W / 17 W: T1…T4
up to 70 °C, the performance specifications have been
evaluated with an ambient temperature of 50 °C Note! Other electrical specifications see data sheet 1.1-183
and 1.1-184
Attention! Long periods of non-actuation can reduce the switching
performance

SURFACE TREATMENT SEALING MATERIAL
◆ The valve body is painted with a two component paint NBR or FKM (Viton) as standard, choice in the type code
◆ The cover, the slip-on coil and the armature tube are zinc-nickel
coated

VALVES INSTALLED
The central functioning element is the poppet valve cartridge NG4, data sheet 1.11-2020.
