If a pilot valve/control unit is used, the max. ambient
temperature is +55 °C.
The angle-seat control valve is suitable for steam
sterilization.
3) Pilot air ports with push-in connector
4) Pilot air ports with threaded bushing.
7.4.2. Control medium
In conjunction with pneumatic control units (positioner or process
controllers), pilot air according to DIN ISO 8573-1 must be used:
Class 3 (for water content)
Class 5 (for dust and oil content).
The specification is described in detail in the operating
instructions of the respective positioner / process controller
in the chapter entitled “Technical Data”.
