The required minimum pilot pressure P
(flow below the seat) is dependent on the pressure of the medium
minimum pilot pressure: flow above the seat
(medium flow with the closing direction of the valve)
The required minimum pilot pressure P
(flow above the seat) is dependent on the pressure of the medium
