Marine and Industrial applications
AMOT Model G rotary 3-way actuated control valves provide a high degree of accuracy for precise temperature control in both mixing and diverting applications over a wide flow range and a variety of fluids. The durable valve is designed to withstand high-vibration applications and is easy to maintain.
Applications:
For engines, turbines, gearboxes and heat exchangers:
-
Charge air cooling
-
Secondary cooling systems
-
Fuel and lube oil preheating
-
Co-generation
-
Engine jacket water
For refineries, chemical plants and oil reporduction:
-
Waste heat boilers
-
Product coolers
-
Product heaters
-
Product condensers
Features and Benefits:
-
Easy to integrate into existing systems
-
Flexible design - ports can be configured to suit installation
-
Simplified set up and maintenance
-
Hand wheel allows manual adjustment of valve (optional on pneumatic valve)
G-valves are delivered in both standard- and high flow-version. The values in the table below are for the high flow-version.
Compact by Design
Designed small for big solutions
-
Compact design opens new piping design possibilities
-
Fits in tight spaces and pipework
-
Lightweight
-
Mounts in any direction, including upside down
High flow - Low pressure drop
-
The flow path through the valve is largely uninhibited by the rotor
-
This offers extremely low pressure drop for given flow rate and valve size
Flexible ports
Design your pipework, then pick your valve mode
-
Flexible ports bring freedom of pipework design
-
The valve meets the pipework design, not vise versa
-
Allows for mirrored installations
-
Allows flow in or out of any port as standard
-
High flow and low flow versions
Reconfigurable on site
Easy installation and comissioning
-
Fully factory tested and set up on delivery
-
In the event of late stage pipework layout change, the G-valve is reconfigurable on site by customer
-
Dip switches for change of direction & control input are available. No laptop needed
Good Vibrations
Designed for ardous On-Engine use
-
Custom designed actuator and valve assembly to endure the harsh vibrations caused by large diesel engines, ships and alike
-
Used in integrated in-engine applications, hard bolted to engine block
Internal Leakage
Every application is different. AMOT offer three options for internal leakage
-
ANSI Class I
-
Better than 2% internal leakage for applications running at constant mixing or diverting
-
-
ANSI Class II
-
0,5% or better internal leakage for applicationwith elevated efficiency requirements
-
-
ANSI Class IV
-
For ultimate efficiency, the LLGG 0,01% internal leakage version is the choice
-
System Integration
AMOT offers different levels of system integration
-
Stand alone system integration including the Valve, the sensors, PID logics, and optional external communication in one package
-
Fully integrated valve only, controlled by others, reading a variety of input signals such as 4-20mA, 0-10V and feedback

Amot GG-valve model code example: (See also table in data sheet p. 17)
06GGSDBS32EABCAAA: 6'' GG-valve, standard flow (S), duktile iron (D), flange PN10 (B), standard rotor (S), rotor position cold (3) rotor position hot (2), actuator 100-120 VAC 50/60Hz (EA), actuator input 4-20mA (B), actuator position output 4-20mA (CA), no customer customizations (AA)
08GGSDCS32EABCAAA: same as above, but 8'' valve with PN16-flange.
Operation:
Model G 3-way temperature control valve acts as an integral part of your electrical, pneumatic or electro-pneumatic system. The electric G-valve system is easy to install, while the pneumatic system is ideal when there is a lack of electricity or when a failsafe system is required. The electro-pneumatic system combines the features and functionality of AMOT's electronic control system with the flawless advantages of a pneumatically actuated valve. The position sensor on both electrical and electro-pneumatic versions allows for direct connection to an engine management system.
