By far the most popular actuator types of electric actuator are the rotary electric actuator, and the linear electric actuator. The rotary actuator is more accurately described currently as an electronic actuator as it more accurately reflects the complexity of modern electrical actuators and is a hugely popular valve actuator because of the general availability of electricity, and is therefore seen in a wide variety of applications in many different industries.
Actuated Valve Supplies, one of the UK’s premier electric actuators suppliers, have decades of experience in the motorised valve actuator markets and have strong connections with several electric actuator manufacturers or valve actuator manufacturers and many actuator suppliers. This enables AVS to offer a wide range of rotary electric actuators typically covering requirements for 12V electric actuators, 24V actuators and 240V actuators, however the main stocked types of electric actuators are multi-voltage capable whereby they will accept a range of supply voltages in a single model.
The automatic actuators offered from stock by Actuated Valve Supplies have actuator torques ranging from 20Nm through to 350Nm and are available as on-off, or as an electric failsafe actuator, or a modulating actuator. Failsafe electric actuators are able to send an actuator to a pre-set ‘safe’ position if external power is lost. Modulating valve actuators have a different function in that their movement is proportional to, and controlled by a control signal. AVS can offer failsafe modulating function, something not available from all valve actuator manufacturers.
Terminology in a specific field can get confusing and the valves and actuators market is no exception. The most common crossover is that the electric actuator is often referred to as an electric solenoid actuator, rotary solenoid actuator or similar, because it is electrically operated. Whilst an electric rotary actuator from Actuated Valve Supplies can be operated to create similar function to a solenoid valve, it would have to be a failsafe electric actuator to allow it to close when de-energised, but there are caveats that need to be understood if the valve actuator is to be used this way.
