Actuator
The EA100 actuator with or without positioner is the actuator we primarily recommend. It withstands vibrations and can be mounted in any position, including pointing downwards. Read more about EA100.
We can deliver G valve with actuators that meet all requirements, including:
- Operating voltage and control signal, including bus communication.
- Extra vibration-resistant, as well as tolerance to shock.
- Electrical and mechanical failsafe.
- Explosion proof.
- Special surface treatment, incl. NORSOK.
Dimensions
Please see data sheet page 7 for dimensions per valve size datasheet
Control system
Fully programmable PID-based control system allows easy system configuration. Universal inputs; RTD’s, thermocouple, or standard 4-20mA signal gives maximum system design flexibility. Can be operated in manual mode, easy maintenance and set up. Read more about control system
About model codes
Page 20 of the datasheet shows how the model code is structured. Below are examples of model code for the standard version.

GEF standard design
GEF valves are 3-way ACV: temperature control valves consisting of a powerful rotary valve and either a quarter turn EL actuator. GPD is the designation for the same valve body with pneumatic actuator.
The GG model is a newer design, but the same construction dimensions and functionality. GEF standard design is made for coolants in fresh water/glycol or oil, for system pressure up to 10 bar, design max temp 100ﹾC and max flow 8 750 m3/h.
- Large selection of sizes and materials.
- Flexible port configuration.
- Can be mounted in any direction, including with the actuator pointing downwards.
- Large flow, low pressure drop.
- Small physical size.
Sizes
The table below shows available sizes in inches and mm, as well as pressure drop in mbar for different amount of flow in m3/h. AMOT G valves are designed to produce minimal pressure drop. The normal recommendation in sizing the valves is to select a pressure drop between 25 - 300 mbar. The normal recommendation for salt water in bronze valves is a max pressure drop at 100 mbar. See datasheet for pressure drop values for oil and other fluids with higher viscosity.
Flanges
EN1092: PN6, PN10 and PN16.
ASME: 125, 150, 300 and 600lb.
JIS: 5 and 10K.
Max pressure is 10 barg, unless otherwise stated, regardless of flange type.
