Powerful, reliable, and versatile – our pneumatic actuators with integrated controls are the ideal solution for precise control and regulation in demanding industrial environments. Their robust design and flexible configuration ensure maximum operational safety and long service life, even under extreme conditions.
Product Features:
Rack and pinion or scotch-yoke design with torque up to 100,000 Nm (higher torques available on request)
Single and double acting versions, fail-safe and fail-close function
Complete systems including positioners, solenoid valves, and limit switches
Compact design for easy installation and maintenance
Corrosion-resistant materials for maximum durability
Precise and reliable operation for advanced process control
Applications:
Oil & gas industry, chemical plants, power generation, water and wastewater treatment, process automation, and offshore installations
Units consisting of valve and actuator, operated electrically, pneumatically, or hydraulically
Closing times of less than 1 second possible, even for electric / power-off closing versions; standalone solutions with their own control logic and power supply (e.g., with solar panels)

Rubber Expansion Joints
The expansion joints are manufactured in various rubber qualities, providing the optimal solution for every application.
An expansion joint is a flexible element designed to compensate for movements in pipelines, particularly those caused by thermal expansion, vibration, wall transitions, or ground settlement. Compensation is achieved mechanically through an elastic bellow.
Depending on the medium, pressure, temperature, and required service life, the expansion joint is made from different materials. In the power plant sector, metal and fabric expansion joints are most commonly used; however, there are also applications where rubber, PTFE, or other plastic expansion joints are preferred.
