The new GEMÜ 1434 µPos electro-pneumatic positioner was specially developed for small and medium size single acting globe and diaphragm valves. This device has dimensions of 42 x 42 x 95mm enabling control valves to be installed in restricted spaces. The device has no superfluous special functions but an intelligent self-calibrating electronic system. The positioner can also be mounted to other valve makes. When idle there is no air consumption, during operation it supplies the pneumatic valve actuators with up to 15ltr/mn. The device is mounted to the actuator by means of a standard thread, the pneumatic connection is via an instant air connector and the electrical connection is via a M12 screwed 5 pin standard plug. It is operated via 24V DC power supply and the set value input signal is 4-20mA. A 24V DC input signal starts automatic initialisation. Colour LED´s clearly indicate the current device status. The housing has an aluminium or stainless steel base and a solid high quality plastic cover.
