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, the cover and the socket head screws are made of NBR or FKM (Viton) as standard, choice in the type code
stainless steel
-The slip-on coil and the armature tube are zinc nickel coated
Optionally K10: MANUAL OVERRIDE
-The coil is made of stainless steel Screw plug (HB0), no actuation possible
Optionally: HB6, HN(K) or HG(K)
→ See data sheet 1.1-311

VALVES INSTALLED
The central functioning element is the poppet valve cartridge NG6, data sheet 1.11-2030.
