VALVE THAT CAN BE INTEGRATED
Pilot.Control
The pilot valves employed in the AirLINE Ex system essentially consist of two components:
• Component 1: the pilot control in protection class Ex-i.
The pilot control converts the supplied electrical energy into a pneumatic switching signal.
The EC-Type Examination Certificates for the pilot controls can be found in the Appendix of these oper-
ating instructions.
• Component 2: the amplifier.
The amplifier is a purely pneumatic element that increases the relatively low flow rate of the pilot control system
to the level necessary for the application.
Because, from an electrical point of view, only the pilot control is important, much information is based upon this,
e. g. boost time or approval-related facts.
The pilot control system is an independent module (e. g. Type 6104). In complete valves (e. g. Type 6525), it may
already be integrated.
Valves.with.auxiliary.control.air.
When using valves in the auxiliary control air version, the exhaust air of the pilot control valve escapes into the
environment.
Valves with auxiliary control air cannot be combined with standard valves (internal auxiliary control air) on the valve
island, as the X port then has a different function.
Further information on the valves can also be found on the Internet under the respective type number.
