Actuators
Single-Acting Pneumatic Actuator
Featuring a spring-return mechanism, this actuator ensures automatic fail-safe operation by returning the valve to its default position in case of air supply failure. Its robust construction and reliable performance make it an excellent choice for critical applications requiring operational safety, such as emergency shutdown (ESD) and fail-safe control systems.
Double-Acting Pneumatic Actuator – 2 Cylinders
Designed for high-torque applications, this model utilizes two parallel cylinders, effectively increasing the force applied to the valve. Ideal for large-diameter or high-pressure valves, it ensures smooth and efficient actuation even under demanding operational conditions. The double-acting function allows precise bidirectional movement, making it suitable for automation in flow control systems.
Double-Acting Pneumatic Actuator – 1 Cylinder
With a compact and lightweight design, this actuator provides reliable performance for industrial applications requiring precise and repetitive valve operation.
Single-Acting Hydraulic Actuator
This heavy-duty actuator is designed for high-force applications where compressed air is not sufficient. The hydraulic pressure enables controlled and powerful actuation, while the spring-return system ensures fail-safe operation by automatically closing or opening the valve in case of hydraulic failure. It is commonly used in safety-critical systems in the oil & gas and power generation industries.
Double-Acting Hydraulic Actuator
Developed for extreme operating environments, this actuator provides high torque and precise valve control, even in high-pressure conditions. By utilizing hydraulic power in both directions, it ensures smooth and controlled movement, making it ideal for large and high-pressure valve operations in offshore platforms, refineries, and industrial automation systems.
Lightweight Aluminum Actuator – Single and Double-Acting
An optimized solution for lighter applications, this actuator is made of high-strength aluminum, reducing overall weight while maintaining excellent durability and corrosion resistance. Available in both single-acting (spring-return) and double-acting versions, it is an economical and efficient option for industries where weight, cost, and performance must be balanced. Its design makes it perfect for general industrial use, water treatment plants, and automated systems.
