Note! With the L15 / L17 execution for ambient temperatures Attention! Long periods of non-actuation can reduce the switching
up to 70 °C, the characteristics have been evaluated performance
with an ambient temperature of 50 °C.
The switching times depend on the volume flow,
pressure and viscosity. In case of small volume flows,
the switching time can get considerably longer.
SURFACE TREATMENT MANUAL OVERRIDE
◆ The cartridge body, the slip-on coil and the armature tube are Screw plug (HB0), no actuation possible.
zinc-nickel coated Optionally HN (K) or HG (K) (pushing) resp. HZ (K) (pulling)
→ See data sheet 1.1-311
Attention! The manual override HZ (K) can neither be dismantled
nor retrofitted
