3.2 Description
The GEMÜ 4240 combi switchbox is suitable for mounting to
pneumatically operated linear actuators. The position of the
valve spindle is reliably detected electronically and reported
via microswitches or proximity switches, using play-free and
non-positive mounting. Integrated pilot valves enable direct
activation of the process valve connected to them. The
product has been designed specially for valves with a stroke
of 5 to 75 mm.
3.3 Function
The GEMÜ 4240 combi switchbox indicates the current posi-
tion of the valve. When the valve is opened, the spindle in the
combi switchbox moves upwards and indicates that the valve
is OPEN using the communication interface. When the valve is
closed, the spring in the mounting kit presses the spindle in
the combi switchbox downwards and indicates that the valve
is CLOSED using the communication interface.
