1.2 Safety
Certain operations within this manual are potentially hazardous and could
cause injury to personnel or damage to equipment if the instructions are not
carried exactly as described. Where a significant, potential hazard exists, the
following text appears immediately before steps in the procedure that present
a particular hazard:
WARNING
A Warning identifies a hazard that could cause injury to personnel.
The text of the warning describes the hazard and details the
precautions that must be applied before the next step of the procedure
is carried out.
CAUTION
A Caution identifies a hazard that could cause damage to equipment.
The text of the caution describes the hazard and details the
precautions that must be applied before the next step of the
procedure is carried out.
Note
A Note contains supplementary information that may be useful to the
Operator before the next step of the procedure is carried out.
1.3 Maintenance
Maintenance of the valve and actuator should only be carried out by suitable
trained and competent persons, and only after they have read and understood
all applicable sections of this manual. Failure to observe this may result in
damage to equipment or to injury of personnel.
1.4 Product Support
All necessary settings and, where appropriate, alterations inside the equipment
are described in this Operating Manual. If any difficulties arise during start-up,
you are asked not to carry out any unauthorised actions on the unit. You could
endanger your rights under the equipment warranty.
For spares and service support, call the telephone number listed on the back
cover of this Manual.
1.5 Typographical Conventions
Footnotes
Where space in the text or figures to place a note is restricted, a footnote is
used. They consist of two parts:
•A mark indicating which part of the text or figure is affected by the note.
This takes the form of a superscript number e.g. Abc 1.
1This footnote applies to the part of the text or figure, marked with a superscript number 1.

the corresponding number in the text (see bottom of page):
1.6 European Union Directives
1.6.1 EU Machinery Directive
The AMOT Model G Valve, as a component, is not considered to be a machine.
To fully comply with the Directive however, the machine into which the valve is
installed must comply with the requirements of the machinery directive before
the valve is put into operation.
1.6.2 Low Voltage Directive
All version of Electric actuator described in this manual have been assessed
against the requirements of the Low Voltage Directive, and have found to be in
conformance.
1.6.3 EMC Directive
All version of Electric actuator described in this manual have been assessed
against the requirements of the EMC Directive, and have found to be in
conformance.
1.6.4 EU Pressure Equipment Directive
In its design application of a temperature control valve, the AMOT Model G
Valve is defined as a Pressure Accessory under the terms of the EU Pressure
Equipment Directive (PED).
Valves used with fluids defined as Group 2 in the Directive (such as water and
lubricating oil) fall into the Sound Engineering Practice (SEP) category.
Some valves are also rated for use with Group 1 liquids under the SEP
category.
Table 1 contains details of the groups each valve type falls into and the
associated maximum working pressure of the valve.

2.1 Description
The G Valve and its ancillary equipment are designed for the control of fluid
temperature by ‘diverting’ or ‘mixing’ control techniques.
The valves can be used for fresh water, most lubricating oils and other liquids.
The compact construction of the G Valve enables unobstructed, full-bore flow,
thus minimising pressure losses.
2.1.1 Features
The G Valve system has the following main features:
•Any direction of rotation.
•Any rotor-port configuration (most models).
•Compact construction.
•Low pressure drop.
•High accuracy (±1°C or better).
•Mountable in any position.
•Manual override.
•Fluid temperature up to 100°C (212°F).
•Local valve position indication.

System Overview
Rev 4 – MAY 2019 OMMGGE00217
2.1.2 Typical Applications
Lubricating Oil Temperature
Control
Lubrication oil temperature control is
normally configured in a mixing
application controlling the return
temperature to the heat load.
The temperature is normally measured
as close as possible to the sump
return.
Jacket Water Cooling
Jacket water cooling in diverting
applications regulates the outlet
coolant water temperature from a
diesel or gas engine. The valve either
sends water to a cooler or bypass
loop, accurately maintaining the
temperature.
The temperature is normally measured
at the outlet from the heat source.
Charge Air Temperature Control
The intercooler is used to cool high
temperature turbo charger air. In this
application, the G Valve regulates the
flow of cooling water through an
intercooler, which can increase
efficiency, enhance performance and
help meet stringent environmental
requirements
Central Cooling
For large flow central cooling, mixing
or diverting applications where
accurate temperature control is
required. The capabilities of the G
Valve provide the ideal solution.
