Pneumatic Actuator ; An actuator is defined as an operator mechanism that provides automation of the opening and closing operations of a valve. The actuator connected to the valve is divided into different types and provides a very effective use. One of them, the Pneumatic actuator, allows the valve to be opened and closed using compressed air.
Pneumatic actuators, of which there are two types, double-acting and single-acting, have different areas of use. Another type of actuator, an electric actuator, allows valve opening/closing operations to be performed with an electric motor. So what are pneumatic and electric actuators, where are they used, what are their characteristics?
The pneumatic actuator is a control element used in the opening/closing operations of valves. Basically, it provides systematic conversion of the energy supplied from the compressed air installation into mechanical movement. In this way, it realizes the automation feature in valve control. It is possible to list the pneumatic actuators, which have many features that provide long-term use, in general terms as follows:
It has an aluminum body.
The shaft is equipped with cadmium-plated steel pistons.
Thanks to its sealing feature, it offers an effective use.
There are two types: Double-Acting and Single-Acting (Spring-Return). The preloaded springs found in Single-Acting Actuators promise a highly effective use because they are specially coated against corrosion. In addition, their cartridge-type design makes it possible to seamlessly add them to covers compatible with standard Single-Acting Actuators.
The working environment of pneumatic actuators is air or non-corrosive gases. In addition, the areas of use are Ball Valves (DN-15-DN 150) and Butterfly Valves (DN40-DN 400). The installation of pneumatic actuators is quite easy. In this way, the installation can be performed by saving time.
The parts located at the bottom of the pneumatic actuator provide long-term and effective use because they are designed in accordance with international ISO5211 standards. In addition, the presence of two square flash connections between the bottom and the holes allows the system to work Decently.
The located connection end of the system is used for the input signal at the top or bottom. Low pressure and double or triple inlet force ensure the operation of the valve.

SPECIFICATIONS Body Aluminum Extrusion Valve Connection TS EN ISO 5211 Shaft Cadmium Plated Steel Pistons Aluminum Die Casting Sealing Nitrile Rubber Valve Connection Namur
WORKING ENVIRONMENT Air or non-corrosive gases
INSTALLATION The installation of the lower part complies with the international ISO5211 standards. There are two square flange connections Decoupled between the bottom and the holes. In double-acting actuators, the air pressure must be directed for on-off or proportional control of the valve.
In single-acting actuators, the preloaded springs are coated against corrosion and can be easily added to the covers suitable for a standard single-acting actuator with cartridge-type designs.
