Attention! If, because of the given operating conditions, during the 80
switching process volume flows occur which exceed
the power limit of the valve, these have to be limited by 60
a throttle or an orifice in connection P.
In case of a continuous flow through, the throttle or 40
orifice, depending on the system behaviour, an 20
additional heating-up of the valve is possible. This has
to be appropriately taken into account by the user. 0 0 50 100 150 200 250 300 350 p [bar]
