Pneumatic Actuators :Double Acting Type PD
Can be used in natural gas, nitrogen, air etc. Services
One of the outstanding features of this type of actuator is its ability to be used in various gas services. This means that these actuators can be used to control the flow of gases such as natural gas, nitrogen, air, and other industrial gases.
Compliant with IGS, IPS and API 6DX standard requirements
Another important feature of PD pneumatic actuators is their compliance with international standards. Standards such as IGS, IPS, and API 6DX define specific technical and safety requirements for equipment used in various industries, including oil, gas, and petrochemical industries.
Design with Scotch-Yoke mechanism suitable for quarter-turn valves
The Scotch-Yoke mechanism is a mechanism that converts linear motion into rotary motion. In pneumatic actuators, the linear motion of the piston is created by air pressure, and then this linear motion is converted into rotary motion by the Scotch-Yoke mechanism. This rotary motion is transmitted to the valve shaft, causing the valve to open and close.
Use of high engagement level rollers to transfer power without slipping
Due to their high friction surface, these rollers transfer the driving force accurately and uniformly to the output shaft. This results in a more precise and controllable actuator movement.
Converting linear force into rotation in a chamber separate from the pressurized cylinder
In conventional pneumatic actuators, the linear force generated by air pressure is directly transmitted to the moving components, causing rotary motion. However, in this specific design, the mechanism that converts linear force to rotary motion is housed in a separate chamber, isolated from the pressurized cylinder. This feature is particularly important in the oil and gas industry where the risk of explosion is high.

Use as an Operator in Ball valves and Butterfly valves
PD pneumatic actuators are widely used as actuators in ball and butterfly valves due to their simple structure, high reliability, and affordable price. These actuators use compressed air to provide the necessary force to open and close the valve.
Oil and Gas and Petrochemical Industries
Double-acting PD pneumatic actuators have found widespread use in the oil, gas, and petrochemical industries due to their unique characteristics. These industries, characterized by harsh working conditions and the need for precise fluid flow control, require equipment with high reliability and performance.
Steel Industries
The steel industry faces challenging and harsh working environments. Extremely high temperatures, suspended particles, corrosive chemicals, and the need for precise process control are among the factors that make the selection of suitable equipment very important. Pneumatic actuators, due to their unique characteristics, are considered the best option for these industries.
