PNEUMATIC POSITIONER F10 :

The Posiflex-Pneumatic Positioner is a simple, single stage, displacement balance instrument suitable for either linear or rotary actuators.It provides stepless positional control for a wide variety of pneumatic actuators. A single universal model can be used for both double acting and single acting applications.

The basic design incorporates a high enhancement flapper and nozzle spool valve and adjustable range and reversing mechanical feedback

Three Position Cam for Rotary Actuators provides for linear, quick opening and equal percentage characteristics. A special cam for rotary actuator provides for split range.

ELECTRO-PNEUMATIC POSITIONER F20 :

The F20 is a universal Electro-Pneumatic Positioner, suitable for either linear or rotary actuators (single or double acting).

The F20 Positioner operates on the principle of analog electronic comparison. An analog 4-20 mA input signal is used to obtain an accurate position of the actuator.

The F20 is a true 2 wire instrument, with the 4-20 mA signal providing both the controlling signal and power supply for the electronics. An electronic module provides all the usual control characteristics; zero, range and sensitivity.They are all electronically resetable using trimmers on the control card.

A comprehensive range of integrated control options include gauges, switches and position transmitters. Mounting is to the Industry standard VDI/VDE 3845 (Namur) or IEC 534/6. The drive coupling for the rotary version is spring loaded for zero backlash.

ELECTRO-PNEUMATIC POSITIONER F40 :

The F40 Intelligent Positioner is the most advanced Electro-Pneumatic Positioner available in the market today. This version is made possible by a combination of the latest developments in microprocessor technology together with a lower power interface for the ultimate in actuator control.

The F40 is an instrument, with the 4-20 mA signal, providing both the controlling signal and power supply for the electronics. Smart functions and modular design enable the standard Positioner to be used on most rotary and linear actuators without modification.

The micro processor senses what is required and sets itself up accordingly.

All the usual control characteristics are provided, these are easily reset-able from the five buttons on the control panel – split range, equal percentage, quick opening, custom curves and direct / reverse acting. A torque seat function for torque seated valves is also available.

Mounting is to the Industry Standard VDI / VDE 3845 (Namur) or IEC 534 / 6. The drive coupling for the rotary version is spring loaded for zero backlash.

PNEUMATIC POSITIONER MODEL (M) :

Pneumatic Positioner Model ‘M’ is ideal for all rotary Actuators and can also be used on linear application. The Positioner has been designed to provide stable, reliable and proportional position control of pneumatic Actuators used in process automation.In a typical process loop, the Positioner compares the output signal from the controller (pneumatic) with the position of the pneumatic final control element and corrects its position. Positioner and final control element together form a position control loop.

The operation of the Positioner is based on a force balanced system i.e. equilibrium is reached when the force from the feedback spring equals the force from the instrument signal capsule.

Limit switches and / or position transmitter can be added on to the Positioner assembly in a separate enclosure.
