PROCESS valve users requiring simple positioners for small pneumatic linear valves normally have to use oversized positioners with many additional unnecessary functions.
This is no longer the case. The new GEM 1434 Pos electro-pneumatic positioner was specially developed for small and medium size single acting globe and diaphragm valves. It only takes two minutes to mount, programme and commission this device which has unusually small dimensions (42 x 42 x 95mm) enabling control valves to be installed in very restricted spaces.
The positioner has no superfluous special functions, but an intelligent self-calibrating electronic system - making it very user-friendly and low cost.
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 15 litres/min. 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 five-pin standard plug.
The GEM 1434 Pos is operated via 24V DC power supply and the set value input signal is 4-20 mA. A 24V DC input signal starts automatic initialization.
