What is an actuator and how does it work?

Actuator is an operator mechanism that automates the opening and closing operations of valves. It is mounted on the valve and connected to the body, and actuated by electrical, air or hydraulic pressure. Thus, valve opening and closing can be controlled remotely via remote control or automation systems without the need for manual intervention.

What are the advantages of electric actuators?

Electric actuators operate with a fixed torque thanks to the electric motor and provide precise control capability. The easy accessibility of electricity everywhere makes their use practical, while their quiet operation features particularly make them preferred in building technologies and precise processes. Additionally, being able to operate in wide voltage ranges, their long-lasting structures, and high rotation angle tolerances make them safe to use in many sectors.

What are the features that distinguish pneumatic actuators?

Pneumatic actuators, due to their lightweight and durable structures as they operate with compressed air, have a wide range of applications. Their prominent advantages include the ability to operate safely in explosive environments, provide emergency shutdown functionality, and have lower operating costs. Although they operate faster than electric actuators, the need for a compressor can increase installation costs and noise levels may be higher.

What are the types of pneumatic actuators?

Pneumatic actuators are basically divided into diaphragm type and piston-cylinder type. Diaphragm type actuators are generally preferred in simple applications requiring low stroke, while piston-cylinder type actuators are used in industrial applications requiring higher force and stroke. Thanks to this variety, pneumatic actuators can be used in conjunction with gate, diaphragm, globe, butterfly, and plug valves.

In which sectors are actuators used?

Actuators play a critical role in many industries such as food, automotive, maritime, HVAC, petrochemical, pharmaceutical, metal industry, energy, and textile. For example, in the food industry, they provide safety with hygienic and easy-to-clean structures, while in the automotive sector, they manage temperature and fluid control on production lines. Offering solutions resistant to high pressure and temperature in the energy and metal industries, they ensure safe operations in maritime appli...

What is the difference between pneumatic and electric actuators?

Electric actuators offer quieter and more precise control, while pneumatic actuators provide faster response and can ensure safe closing function in emergency situations. Pneumatic systems may be advantageous in terms of operating cost, but the need for a compressor can increase installation costs. Electric actuators, on the other hand, have a longer lifespan and are widely preferred as electricity is easily available in any environment. These differences allow for selection based on the appl...

Actuators

Actuator is an operator mechanism that provides automation of the opening/closing process of the valve. It is mounted on the valve and connected to the valve body. There are different types of actuators and different uses of these types. Power driven actuators are basically divided into three.

Electric Actuator
Uses the electric motor to open and close the valve.

Pneumatic Actuator
Uses pneumatic systems operated by compressed air to open and close the valve.

Hydraulic Actuator
Uses hydraulic systems operated by pressurized fluid to open and close the valve.

Electric Actuator

Electric Actuators use an electric motor to open and close the valve. The drive force obtained by the electric motor ensures the circular movement of the gears within the body. Since the gear system is used, a constant torque rotation is provided from the beginning to the end of the opening/closing process. Electric actuators, which can be used with many different valves such as butterfly and ball valves, perform the valve open-close operation slower than pneumatic and hydraulic actuators due to the gear systems inside them.

Pneumatic Actuator

Pneumatic Actuators are actuators operated by compressed air. Pneumatic actuators are preferred in most applications due to their light and durable structure. Their advantages are that they are cost-effective and reliable, can be used in explosive environments, and can be used as an emergency closing actuator (fail-safe).

Single-acting pneumatic actuator is produced as a model that opens/closes with spring force. In this way, the actuator is in the open or closed position unless it is operated. When these actuators are operated, they become closed if they are open and open if they are closed. It is the spring inside that allows it to return to its original state.

Since pneumatic actuators work with a compressor, the installation cost is slightly higher, but since they use air as raw material, the operating cost is low. They are noisier than electric actuators.
