Air connection
Solenoid pilot valve and matching connection thread
4/2-way or 5/2-way solenoid valves are used to control double acting actuators (DA). They
can be mounted either directly to the actuator via a Namur connector plate or via valve
clusters.
The DA-mode of operation with a 4/2- or 5/2-way solenoid valve.
Both connections are used

Control medium
Information
• 5 bar max. for the DA­mode. For DN50 and from a line pressure of 10 bar the control
pressure is 6 bar max.
• When pressure exeeds 10 bar the controll pressure must be throttled by exhaust air
(adjust actuating time to approx. 3 s)
• Compressed air class (ISO 8573­1) 2 or 3 for –10 °C and 3 or 4 for T ›0 °C
• Temperature of control medium, max. 40 °C
• Depending on the working pressure PN, lower control pressure may be selected
• Please consider the control pressure diagrams in the chapter "6.6 Control pressure
diagrams" or in the Georg Fischer Planning Fundamentals
