The Omal “Rackon” actuators use a Rack & Pinon design to transform a linear motion generated by the actuator pistons directly into a rotational output shaft motion 0°÷90°.

Standard actuators (DA and SR) have a clockwise rotation (CW) direction to close the valves (0° closed valve, 90° opened valve), but counter-clockwise rotation (CCW) versions (0° opened valve, 90° closed valve) are available too.

DA 10Nm to 474Nm, SR 15Nm to 347Nm

Air supply 2 bar to 8 bar

Temperature range -20°C to +80°C

ATEX available

General Pressure Sensor

Magnetostrictive continuous level transmitters base their operation on the physical principle called Wiedemann effect and allow a continuous and precise measurement of liquid levels. The electronic unit sends a pulse to a waveguide contained in the measuring rod; the magnetic float intercepts the pulse generating an echo that is detected by the same electronic unit. The elapsing time between the emission of the pulse and its recognition is directly proportional to the position of the float, and then to the value of the level to be measured.

PVC – PP – PVDF

2 analog outputs, current and voltage

RS485 serial output, Valco protocol

Up to 2, 9 m length

Working pressure up to 6 bar depending on the used float

Aluminium body

The new and updated Omal aluminium standard spring return pneumatic actuator - now with an integrated NAMUR interface and adjustable end of travel stops - from SRN15 and bigger, to 4000Nm.

Torque output from 15Nm to 4000Nm. Torque: the return torque depends on spring action only not withstanding the air supply. The spring is provided in four different sizes.

Torque output 15Nm to 4000Nm

Air supply 5,6 bar; maximum 8,4 bar

Temperatue range 0°C to +80°C

ATEX available on request

General Pressure Sensor

The principle operation of the LCD-S level switch is based on the moderate shutdown of a series of resistors and reed contacts. These are placed inside the guiding rod by a magnetic float. The only moving parts will be the float which moves along the measuring rod. You can program the sensor manually or via the “MYVALCO” app using NFC technology, available on Android® app store.
