Valve Positioners

Rotary / Linear Type Elector – Pneumatic Valve Positioner

4Matic Electro-Pneumatic Positioner (4-20 m Amp, linear and rotary type) are advanced control devices which provide unparalleled stability In difficult environment.

Description

The “4Matic” AEP-1000-R/L series Electro-pneumat ic are used as final controlling element for operation of pneumatic Rotary/linearvalve actuators in correspondence withan input Signalof 4-20mA DCor split ranges.

The Positioners are based on a force balance design for control application that requires a high degree of reliability and repeatability at an economicalcost.

The Positioners can handlethe supply pressure upto 100 psigfor higher pressure industrial pneumatic and process control system requirements.

Principle of Operation

The operation of “4Matic” AEP-1000-R/L series positioners is based on a force balanced system. Tension on the feedback spring provides feedback to the positioner which will vary as the actuator shaft rotates with cam. The spring Loading force is applied through the cam shaft & cam to the positioner’s instrument signal capsule through the balance beam.

Input of 4-20mA DC is applied to the instrument and corresponding output is applied to the control capsule serving as force balance membrane and matching the actuator shaft position to the instrument signal.

Field Reversible

To change form direct acting to reverse acting simply reverse the cam and fix it on cam shaft and make sure of the signal SPAN which is printed on the cam and recalibrate for Actuator fully open or close position incase of Pneumatic to Pneumatic, Positioner Control Valve. For Electro- Pneumatic change current signal input leads form positive to negative and change current signal form 4-20 to 20-4 over and above cam reverse and recalibrate the Positioner.

Features

Rotary / Linear Pneumatic – Pneumatic Valve Positioner

4MatiC Pneumatic-Pneumatic Positioner (3-15 pst I rotary off linear type) are advanced control devices which provide unparalleled stability in difficult environment.

Description

The “4Matic” APP-1200-R/L sesries positioners converts a controller output (usually 3 to15 psigto Linearly/Rotary proportional Trave/Rotational & Pneumatic outputs. The Positioners are based on a force balance desing for control applications that requires a high degree of reliability & repeatability at an economical cost. Optional NEMA 4X (IP65/IP66)-explosion proof versions allows for splashdown/explosive atmosphere and outdoor installation.

The “4Matic” APP-1200-R/L series positioners are used for Liner/Rotary movement with ranges 3-9 and 9-15 psig. control Sigal, when you select split range. Standard rang is 3-15 psig. The positioners can handle the supply pressure upto 100 psigfor higher pressure Industrial pneumatic and process control system requirements.

Principle of Operation

The operation of “4Matic” APP-1200-R/L series positioners is based on a force balanced system.Tension on the feedback spring provides feedback to the positioner which will vary as the actuator shaft rotates with cam. The spring Loading force is applied through the cam shaft & cam to the positioner’s instrument signal capsule through the balance beam.

Output form the controller (usually 3-15 Psig) is applied to the diaphragm in the instrument signalcapsule serving as a force balance membrane, matchingthe actuator shaft positionto the instrument signal.

Split Ranging

If split ranging is required may be mounted on Linear Actuator/Rotary Actuator as per installation and operational manual.
