Marine and industrial applications
AMOT Model G rotary 3-way actuated control valves provide high 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
- Preheating of fuel and lubricating oil
- Cogeneration
- Engine coolant
For refineries, chemical plants and oil refining:
- Waste heat boilers
- Product coolers
- Product warmers
- Product capacitors
Features and benefits:
- Easy integration with existing systems
- Flexible design: ports can be configured to suit the installation
- Simplified setup and maintenance
- Hand wheel enables manual adjustment of the valve (optional on pneumatic valve)
- G-valves are supplied in both standard and high flow versions. (The values in the table below are for the high flow version)
Compact design
Small in scope – designed for large solutions!
- Compact design facilitates new tube street designs
- Fits easily into tight spaces
- Low weight
- Can be installed in any direction - even upside down!
High flow - low pressure drop
- The fluid flow through the valve is practically unimpeded by the rotor
- Extremely low pressure drop for a given flow rate and valve dimension
Flexible gates
Design tube streets first - decide valve mode later!
- Flexible doors give freedom in terms of pipe installation
- The valve meets the pipe construction, not the other way around
- Enables mirror installations
- Flow in or out of any port can be set as default
- Available in both high flow and low flow versions
Compact design
Compact design facilitates new tube street designs
- Fits easily into tight spaces
- Low weight
- Can be installed in any direction - even upside down!
Reconfigurable on site
Easy installation and commissioning
Fully factory tested and set up on delivery. In case of changes to the pipeline, the customer can configure the G-valve on site. Dip switches for direction change and control input are available. No laptop required.
Good Vibrations
- The actuator and valve assembly is designed to withstand the severe loads created by large diesel engines, ships etc.
- Can be used as part of integrated "on engine" applications, bolted directly to the engine block
Internal leakage
All applications are different. AMOT offers three options for internal leakage:
ANSI Class I: Less than 2% internal leakage for constant mixing or distribution applications
ANSI Class II: 0.5% or less internal leakage for applications with increased efficiency requirements
ANSI Class IV: For optimum efficiency, LLGG with less than 0.01% internal leakage is the natural choice
System integration
AMOT offers different levels of system integration
- "Stand alone" system that includes valve, sensors, PID controllers and options for external communication in one package
- Fully integrated valve that can be controlled by a number of different signals, such as 4-20mA, 0-10V or relay control. 4-20mA feedback, as well as position switches

06GGSDBS32EABCAAA: 6'' GG valve, standard flow (S), ductile 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 adaptations (AA)
08GGSDCS32EABCAAA: same as above, but 8'' valve with PN16 flange.
Operation:
The Model G 3-Way Temperature Control Valve works as an integral part of your electric, pneumatic or electro-pneumatic system. The electric G-valve system is easy to install, while the pneumatic system is ideal when there is a shortage of electricity or when a fail-safe system is required. The electro-pneumatic system combines the features and functionality of AMOT's electronic control system with the fail-safe advantages of a pneumatically actuated valve. The position sensor on both electric and electro-pneumatic versions allows for direct connection to a motor control system.
