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 position 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.
