Valves type MH2−...
Valves of type MH2−... have constant leakage of up to 10
l/h in the pressure range −0.5 ... + 0.5 bar. This leakage is
due to the design.
Please note:
The following sequence is recommended for commis
sioning valves of type MH2−... :
S Switch on first the compressed air supply and then
the operating voltage.
You will then avoid leakage of up to 30 l/h in the non−
switched status with operating pressures between −1
bar and +1 bar. By switching on just once you can rem
edy the leakage immediately.
