Pilot valve/manual override

For safety circuits, only pilot valves
without manual override shall be
used.

Devices with pilot valve

The pilot valve, which consists of an e/p binary
converter

 

and a pressure reducer

, is op-

tionally provided with a manual override 

(see Fig. 17).
When a nominal signal is not available, the 
pilot valve can be operated by a pushbutton or
a pushbutton switch using a screwdriver
(4.5 mm blade).
