Technicaldata
Required minimum pilot pressure depending on medium pressure
The following graphs illustrate the required minimum pilot pressure
depending on the medium pressure for control functions B and I.
The values apply to body made of
• forged steel (VS)
• precision casting (VG)
When using Type 2103, 2104 or 2105 as a control valve,
pressure conditions may deviate in some cases. These con-
ditions appear in the diagrams with a gray background.
