PRODUCT OVERVIEW
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.
APPLICATIONS & KEY FEATURES
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.

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. The non-linear configuration is appli-
cable to 3-way valves. Otherwise, in all other circumstances, the Linear
Stem Lift (factory default) will be the desired setting.
In either case, correct control valve sizing is critical to good operation.
See individual product specifications for details on the control valve
assemblies and Cv tables. This document will focus on the installation,
operation, and maintenance of the actuator portion only.

Page 2: Description
DESCRIPTION The AmurAct actuation system is comprised of two principal age converts rotary force and motion to linear force and motion components. The first is an electrical/electronic motor, which to operate the reciprocating stem of an attached globe-style produces torque (rotational force) and applies it to the input valve. -

The articulated link connection components and parts. reduces side loading on the valve stem packing. Raising the stem of a two-way valve opens it. Raising the stem of a three-way valve opens Four AmurAct MOTORS are available: the F3 and F5 produce 120 the lower (L) port and shuts the upper (U) port. -
Page 4: Safety Precautions
STOP READ ALL OF THE FOLLOWING SAFETY PRECAUTIONS BEFORE PROCEEDING! SAFETY PRECAUTIONS READ THIS PAGE BEFORE PROCEEDING! Good engineering practice dictates that isolation valves must be installed in inlet and outlet piping connected to the AmurAct control valve. A means should be provided to de-pressurize line media trapped between them when they are shut. Pressure can cause the valve stem and any attached mechanism to move with force, posing a threat to safety. -
