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 datasheet page 7 for dimensions per valve size.

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

Model G - explosion proof - Ex

G valves are 3-way ACV: temperature control valves consisting of a powerful rotary valve and either a quarter turn EL or PNEU actuator.

WARNING: The valve housing is explosion-proof, NOT the actuator. The right actuator must be selected according to the applicable requirements.

Contact Ing Westad AS for a dialogue about the best actuator solution for your project.

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.
