1.2 Safety
Some operations in this manual can be hazardous and cause injury to people
or damage to equipment if the procedure is not done exactly as written. Where
there is a hazard, the following text appears immediately before the steps in a
procedure that can cause a hazard:

Introduction
Rev 5 – MAY 2019 OMMGGP00185
WARNING
A Warning identifies a step in a procedure that can cause injury to
people. The warning identifies the hazard and lists the precautions
that must be taken before the next step of the procedure is done.
CAUTION
A Caution identifies a step in a procedure that can cause damage to
equipment. The caution identifies the hazard and lists the precautions
that must be taken before the next step of the procedure is done.
Note
A Note contains more information that may be useful to the Operator and
can appear before or after a procedure step.
When installing, commissioning, operating or carrying out maintenance on the
unit, personnel must use safe working practices and observe all relevant local
health and safety requirements and regulations.
1.3 Product Support
All necessary settings are described in this 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 rapid spares and service support, call the telephone number listed on the
back cover of this manual.
1.4 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.
A note in smaller font at the bottom of the affected page beginning with
the corresponding number in the text (see bottom of page):
1 This footnote applies to the part of the text or figure, marked with a superscript number 1.

1.5 European Union Directives
1.5.1 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.
1.5.2 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 supporting 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).
Mount in any position.
Optional manual override.
Temperature up to 100 C (212 F).
Local valve position indication.

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.
