Warren-controls AmurAct Actuator Linkage and Motor User Manual download pdf

The AmurAct actuator is a fast stroking industrial electric actuator

mated to four different series of industrial control valves ranging in

size from ½” to 4” depending on series and profile. The new generation

of Motors covered in this IOM allow the user to select either a linear

stem lift or a non-linear stem lift by means of a dipswitch. Linear stem

lift is the factory default dipswitch selection. Linear stem lift means

the stem position is linear with respect to the input signal. For exam-

ple if the valve is closed with a 0% input signal, the valve will be at 25%

Stroke with a 25% input signal, at 50% Stroke with a 50% input signal,

at 75% Stroke with a 75% input signal, and at 100% Stroke with a 100%

input signal. Linear stem lift preserves the inherent flow characteristic

of the valve. This feature is applicable only to 2-way valves.

When non-linear stem lift is selected the actuator has an ever gain

changing stroke curve that accelerates in the last half of the stroke

and is relatively slow on startup. Extreme gain changes as present in

the Non- liner configuration are difficult for a control system to man-

age. If an application’s turndown requirements are only 3:1 to 5:1 for

example such that a valve could be sized to only operate from 50%

to 100% of stroke, some level of speed of response can be achieved

in the Non-linear configuration. Otherwise, in all other circumstances,

the Linear Stem Lift (factory default) will be the desired setting.

AMURACT IOM

AmurAct Actuator

Linkage and Motor

This product serves a variety of applications very well but is particu-

larly well suited to semi-instantaneous water heaters, heat exchangers

and coils where response times to load changes are expected to be

handled in two to three seconds. With the High Temperature LE link-

age option, thermal fluids, superheated steam and high temperature

hot water are safely served. With the NEMA 4X Option, many hose

down and outdoor applications are possible.

* Enerdrive® Failsafe System for Fail Close or Open (selectable)

* Full Range of AC and DC Voltage Supplies Available

* Universal Input (Voltage or Milliamp) and pushbutton stroke
